question
solve for x.
-4(5x - 4) + 5x + 3 = 34

Explanation:

Step1: Distribute -4

$-4\times5x+(-4)\times(-4)+5x + 3=34$
$-20x + 16+5x+3 = 34$

Step2: Combine like - terms

$(-20x+5x)+(16 + 3)=34$
$-15x+19 = 34$

Step3: Subtract 19 from both sides

$-15x+19-19=34 - 19$
$-15x=15$

Step4: Divide both sides by -15

$\frac{-15x}{-15}=\frac{15}{-15}$
$x=-1$

Answer:

$x = - 1$
