Solve for x: 16 = x + 32 a. 16 b. 2 c. -2 d. -16

The answer would be D. -16

The reason is because to find the value of a variable, you need to isolate it on one side of the equation. To do this, you need to get rid of the 32, and so you would subtract. BUT, if you subtract from one side, you need to subtract on both sides. 16-32= -16, therefore the answer would be D. -16

17 is c. congruent means equal in size
