Solution for in(x-1)+in(x-3)=in(3x+15) equation:


Simplifying
in(x + -1) + in(x + -3) = in(3x + 15)

Reorder the terms:
in(-1 + x) + in(x + -3) = in(3x + 15)
(-1 * in + x * in) + in(x + -3) = in(3x + 15)
(-1in + inx) + in(x + -3) = in(3x + 15)

Reorder the terms:
-1in + inx + in(-3 + x) = in(3x + 15)
-1in + inx + (-3 * in + x * in) = in(3x + 15)
-1in + inx + (-3in + inx) = in(3x + 15)

Reorder the terms:
-1in + -3in + inx + inx = in(3x + 15)

Combine like terms: -1in + -3in = -4in
-4in + inx + inx = in(3x + 15)

Combine like terms: inx + inx = 2inx
-4in + 2inx = in(3x + 15)

Reorder the terms:
-4in + 2inx = in(15 + 3x)
-4in + 2inx = (15 * in + 3x * in)
-4in + 2inx = (15in + 3inx)

Solving
-4in + 2inx = 15in + 3inx

Solving for variable 'i'.

Move all terms containing i to the left, all other terms to the right.

Add '-15in' to each side of the equation.
-4in + -15in + 2inx = 15in + -15in + 3inx

Combine like terms: -4in + -15in = -19in
-19in + 2inx = 15in + -15in + 3inx

Combine like terms: 15in + -15in = 0
-19in + 2inx = 0 + 3inx
-19in + 2inx = 3inx

Add '-3inx' to each side of the equation.
-19in + 2inx + -3inx = 3inx + -3inx

Combine like terms: 2inx + -3inx = -1inx
-19in + -1inx = 3inx + -3inx

Combine like terms: 3inx + -3inx = 0
-19in + -1inx = 0

Factor out the Greatest Common Factor (GCF), '-1in'.
-1in(19 + x) = 0

Ignore the factor -1.

Subproblem 1

Set the factor 'in' equal to zero and attempt to solve: Simplifying in = 0 Solving in = 0 Move all terms containing i to the left, all other terms to the right. Simplifying in = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(19 + x)' equal to zero and attempt to solve: Simplifying 19 + x = 0 Solving 19 + x = 0 Move all terms containing i to the left, all other terms to the right. Add '-19' to each side of the equation. 19 + -19 + x = 0 + -19 Combine like terms: 19 + -19 = 0 0 + x = 0 + -19 x = 0 + -19 Combine like terms: 0 + -19 = -19 x = -19 Add '-1x' to each side of the equation. x + -1x = -19 + -1x Combine like terms: x + -1x = 0 0 = -19 + -1x Simplifying 0 = -19 + -1x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
