Question

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

(x + 2)(x - 3) = 0
m + 7 = -12
b ÷ (-2) = 18
-3 + y = 7

Answer 1

The third one; b÷(-2)=18

Answer 2

b ÷ (-2) = 18

Explanation:

find the equation that uses the multiplication property of equality

`(x + 2)(x - 3) = 0`

To solve for x we set each factor =0. Here we use zero factor property

`m + 7 = -12`

To solve for m , we subtract 7 from both sides. Here we use subtraction property of equality.

b ÷ (-2) = 18

`(b)/(-2) =18`

HEre the expression has division. To remove the denominator we multiply both sides by -2. So we use multiplication property of equality.

`-3 + y = 7`

To solve for y , we add 3 on both sides . WE use addition property of equality.
