Question

16)Which number(s) from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, if any, will solve this equation?2x + 3 = 5x - 3

Answer 1

2

Explanation:

2 (2) + 3 = 5 (2) -3

4 + 3 = 10 - 3

7 = 7

Answer 2

Solve the equation first. 2x + 3 = 5x - 3; add 3 to both sides to get 2x + 6 = 5x; subtract 2x from both sides to get 6 = 3x; divide both sides by 3 to get x = 2 So only the number 2 will solve this equation.
