X by itself is 1, otherwise it is the number to the left
-3(x - 4) + 15 = 3x - 14 + 2x
Multiply the -3 into (x - 4)
-3x + 12 + 15 = 3x - 14 + 2x
Combine like terms
-3x + 27 = 5x - 14
Add 3x on both sides
-3x + 27 + 3x = 5x - 14 + 3x
27 = 8x - 14
Add 14 on both sides
27 + 14 = 8x - 14 + 14
41 = 8x
Divide 8 on both sides
It will take them a total of 3.07 hours.

g2 = 13 + -12g
Solving
g2 = 13 + -12g
Solving for variable 'g'.
Reorder the terms:
-13 + 12g + g2 = 13 + -12g + -13 + 12g
Reorder the terms:
-13 + 12g + g2 = 13 + -13 + -12g + 12g
Combine like terms: 13 + -13 = 0
-13 + 12g + g2 = 0 + -12g + 12g
-13 + 12g + g2 = -12g + 12g
Combine like terms: -12g + 12g = 0
-13 + 12g + g2 = 0
Factor a trinomial.
(-13 + -1g)(1 + -1g) = 0
Subproblem 1Set the factor '(-13 + -1g)' equal to zero and attempt to solve:
Simplifying
-13 + -1g = 0
Solving
-13 + -1g = 0
Move all terms containing g to the left, all other terms to the right.
Add '13' to each side of the equation.
-13 + 13 + -1g = 0 + 13
Combine like terms: -13 + 13 = 0
0 + -1g = 0 + 13
-1g = 0 + 13
Combine like terms: 0 + 13 = 13
-1g = 13
Divide each side by '-1'.
g = -13
Simplifying
g = -13
Subproblem 2Set the factor '(1 + -1g)' equal to zero and attempt to solve:
Simplifying
1 + -1g = 0
Solving
1 + -1g = 0
Move all terms containing g to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + -1g = 0 + -1
Combine like terms: 1 + -1 = 0
0 + -1g = 0 + -1
-1g = 0 + -1
Combine like terms: 0 + -1 = -1
-1g = -1
Divide each side by '-1'.
g = 1
Simplifying
g = 1Solutiong = {-13, 1}
