Question

1. (2 points) solve the following equations a. - 5x + 4 + 2x = 16

Explanation:

Step1: Combine like - terms

$-5x + 2x+4=16$ simplifies to $-3x + 4=16$.

Step2: Isolate the term with x

Subtract 4 from both sides: $-3x+4 - 4=16 - 4$, resulting in $-3x=12$.

Step3: Solve for x

Divide both sides by - 3: $\frac{-3x}{-3}=\frac{12}{-3}$, so $x=-4$.

Answer:

$x = - 4$
