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

Answer:

b ÷ (-2) = 18

Step-by-step 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

$\frac{b}{-2} =18$

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.
