solve the equation.\n5x + 8 - 3x = -10\no x = -9\no x = -1\no x = 1\no x = 9

Explanation:

Step1: Combine like - terms

$5x+8 - 3x=-10$ becomes $(5x - 3x)+8=-10$, so $2x+8=-10$.

Step2: Subtract 8 from both sides

$2x+8 - 8=-10 - 8$, which simplifies to $2x=-18$.

Step3: Divide both sides by 2

$\frac{2x}{2}=\frac{-18}{2}$, so $x = - 9$.

Answer:

A. $x=-9$
