Answer

$$x = -3$$

Work Step by Step

The first step to solving this equation is to group like terms: $$(2x + 3x) + (-5 + 7) = (10x - 6x) + (3 - 4)$$ Combine like terms: $$5x + 2 = 4x - 1$$ Subtract $4x$ from both sides to get $x$ on one side of the equation: $$x + 2 = -1$$ Subtract $2$ from both sides to solve for $x$: $$x = -3$$
