Answer
$x=2$
Work Step by Step
Distribute $3$ to obtain:
$3x-15+2=1-(4+2x)
\\3x-13=1-(4+2x)$
Subtract each term of the binomial to obtain:
$3x-13=1-4-2x
\\3x-13=-3-2x$
Add $2x$ and $13$ to both sides of the equation then combine like terms to obtain:
$3x-13+2x+13=-3-2x+2x+13
\\5x=10$
Divide $5$ to both sides:
$\frac{5x}{5}=\frac{10}{5}
\\x=2$
