linear equations w/ distribution (lev 2)
score: 0/4 penalty: none
question
solve for x.
5(-2x + 4)-x + 3 = 34
answer attempt 1 out of 2

Explanation:

Step1: Distribute 5

$5\times(-2x)+5\times4 - x + 3=34$
$-10x + 20 - x+3 = 34$

Step2: Combine like - terms

$(-10x - x)+(20 + 3)=34$
$-11x+23 = 34$

Step3: Isolate the term with x

Subtract 23 from both sides:
$-11x+23 - 23=34 - 23$
$-11x = 11$

Step4: Solve for x

Divide both sides by - 11:
$x=\frac{11}{-11}$
$x=-1$

Answer:

$x = - 1$
