Question

here is how zee solved an equation.
circle the mistake and explain why zee’s work is wrong.
zee
$-2(3x - 5) = 4(x + 3) + 8$
$-6x + 10 = 4x + 12 + 8$
$-6x + 10 = 4x + 20$
$10 = -2x + 20$
$-10 = -2x$
$5 = x$
what is the correct solution?

Explanation:

Answer:

Zee's mistake is in the fourth line, $10 = -2x + 20$. When moving $-6x$ to the right side of the equation, it should be added to $4x$, resulting in $10x$, not subtracted.
$x = -1$
