Question

linear equations w/ distribution (lev 2)
question
solve for x.
4(3x + 4)+x + 5=-5
answer
attempt 1 out of 3
x =

Explanation:

Step1: Distribute the 4

$4\times3x+4\times4 + x+5=-5$, which simplifies to $12x + 16+x + 5=-5$.

Step2: Combine like - terms

$(12x+x)+(16 + 5)=-5$, so $13x+21=-5$.

Step3: Subtract 21 from both sides

$13x+21 - 21=-5 - 21$, resulting in $13x=-26$.

Step4: Divide both sides by 13

$\frac{13x}{13}=\frac{-26}{13}$, so $x=-2$.

Answer:

$x = - 2$
