Studdy Solution

STEP 1

Assumptions1. We are solving for the variable x in the equation -3(-x+4)-5x+5=-15. We assume that the equation is linear and has a unique solution for x

STEP 2

First, distribute the - across the terms inside the parentheses.
(x+4)=x+4-(-x+4) = -*-x + -*4

STEP 3

implify the expression.
3x+3=3x12-3*-x + -3* =3x -12

STEP 4

Substitute this back into the original equation to get a new equation.
3x12x+=153x -12 -x + = -15

STEP 5

Combine like terms on the left side of the equation.
3x5x12+5=153x -5x -12 +5 = -15

STEP 6

implify the expression.
2x=15-2x - = -15

STEP 7

Add7 to both sides of the equation to isolate the term with x on one side.
2x7+7=15+7-2x -7 +7 = -15 +7

STEP 8

implify the equation.
2x=8-2x = -8

STEP 9

Finally, divide both sides of the equation by -2 to solve for x.
x=8/2x = -8 / -2

STEP 10

Calculate the value of x.
x=4x =4The solution to the equation is x =4.
