To make the expressions equivalent, we need to set them equal to each other and find the value of g that satisfies this equation.
-3(x-4) + 2 = -3x + 14 - g
Expanding the left side of the equation:
-3x + 12 + 2 = -3x + 14 - g
Combining like terms:
-3x + 14 = -3x + 12 - g
At this point, we can see that -3x is present on both sides of the equation. If we subtract -3x from both sides, it will cancel out:
14 = 12 - g
To isolate g, we need to move 12 to the left side:
14 - 12 = - g
2 = - g
To find the value of g, we multiply both sides of the equation by -1:
-2 = g
Therefore, the value of g that makes the expressions equivalent is -2.
