Kira solved the equation in the following way. 7 2 − 2x = 11 2 7 2 − 7 2 − 2x = 11 2 − 7 2 −2x ÷ −2 = 4 2 ÷ − 2 x = −1 Describe the properties of equality that Kira used. The first step is to use the property of equality to combine the constant terms. The second step is to use the property of equality to isolate the variable.

the first step is to use the

✔ Subtraction

property of equality to combine the constant terms.

The second step is to use the

✔ Division

property of equality to isolate the variable

Step-by-step explanation:

edge 20 20

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
