Question 8 • Mathematics 8
Starting with 3x − 5 = −2x + 10, add 2x to both sides and add 5 to both sides to get 5x = 15, which is choice D. Reversing the sides and multiplying both sides by −1 gives −15 = −5x, choice E. In each equation, the variable term is on one side and the constant is on the other.
