Which is a reasonable first step that can be used to solve the equation 4x+3(x+2) = 5(2x-3)?
O Distribute the 3 to x + 2, and distribute the 5 to (2x - 3).
O Combine 4x and x on the left side of the equation.
O Apply the subtraction property of equality to move the 2 from the left to the right side of the equation.
O Apply the addition property of equality to move the 3 from the right to the left side of the equation.
