Answer:
g = 6
Step-by-step explanation:
you need to combine like terms then isolate the variable. so, you can apply “add the opposite” and change the subtractions to additions and the number to its opposite notation.
-25g - (-8)g - (-7)g - (-29) = -31
-25g + 8g + 7g + 29 = -31
(combine like terms)
-10g + 29 = -31
(move the constant to the right by subtracting it from both sides of the equal sign)
-10g + (29 - 29) = -31 - 29
(isolate the variable by dividing by the coefficient)
-10g/-10 = -60/-10
g = 6
(check your answer by substituting 6 into the variables)
