Question

The multiplication property of equality could be used to solve which of the following equations?

A. (x+2)(x-3)=0
B. m +7 = -12
C. b ÷ (-2) = 18
D. -3 + y = 7

Answer 1

Explanation:

C.

The multiplicative property states that by multiplying both sides of an equation gives you the same sum on both sides. By multiplying both sides by -2, the equations are the same by the property.

Answer 2

option C

Explanation:

The multiplication property of equality states that same number is multiplied on both sides of the equation

A. (x+2)(x-3)=0

To solve for x we set each factor =0

B. m +7 = -12

To solve for m we subtract 7 from both sides, Its subtraction property

C. b ÷ (-2) = 18

To remove -2 we multiply both sides by -2 because -2 is in the denominator. we use multiplication property of equality

D. -3 + y = 7

To solve for y we add 3 on both sides, its addition property
