3-(2t+5)=7(t+2t)

Solution for 3-(2t+5)=7(t+2t) equation:

Simplifying
3 + -1(2t + 5) = 7(t + 2t)

Reorder the terms:
3 + -1(5 + 2t) = 7(t + 2t)
3 + (5 * -1 + 2t * -1) = 7(t + 2t)
3 + (-5 + -2t) = 7(t + 2t)

Combine like terms: 3 + -5 = -2
-2 + -2t = 7(t + 2t)

Combine like terms: t + 2t = 3t
-2 + -2t = 7(3t)

Remove parenthesis around (3t)
-2 + -2t = 7 * 3t

Multiply 7 * 3
-2 + -2t = 21t

Solving
-2 + -2t = 21t

Solving for variable 't'.

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

Add '-21t' to each side of the equation.
-2 + -2t + -21t = 21t + -21t

Combine like terms: -2t + -21t = -23t
-2 + -23t = 21t + -21t

Combine like terms: 21t + -21t = 0
-2 + -23t = 0

Add '2' to each side of the equation.
-2 + 2 + -23t = 0 + 2

Combine like terms: -2 + 2 = 0
0 + -23t = 0 + 2
-23t = 0 + 2

Combine like terms: 0 + 2 = 2
-23t = 2

Divide each side by '-23'.
t = -0.08695652174

Simplifying
t = -0.08695652174
