Solution for (r+3-t).4= equation:


Simplifying
(r + 3 + -1t) * 0.4 = 0

Reorder the terms:
(3 + r + -1t) * 0.4 = 0

Reorder the terms for easier multiplication:
0.4(3 + r + -1t) = 0
(3 * 0.4 + r * 0.4 + -1t * 0.4) = 0
(1.2 + 0.4r + -0.4t) = 0

Solving
1.2 + 0.4r + -0.4t = 0

Solving for variable 'r'.

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

Add '-1.2' to each side of the equation.
1.2 + 0.4r + -1.2 + -0.4t = 0 + -1.2

Reorder the terms:
1.2 + -1.2 + 0.4r + -0.4t = 0 + -1.2

Combine like terms: 1.2 + -1.2 = 0.0
0.0 + 0.4r + -0.4t = 0 + -1.2
0.4r + -0.4t = 0 + -1.2

Combine like terms: 0 + -1.2 = -1.2
0.4r + -0.4t = -1.2

Add '0.4t' to each side of the equation.
0.4r + -0.4t + 0.4t = -1.2 + 0.4t

Combine like terms: -0.4t + 0.4t = 0.0
0.4r + 0.0 = -1.2 + 0.4t
0.4r = -1.2 + 0.4t

Divide each side by '0.4'.
r = -3 + t

Simplifying
r = -3 + t
