This time, we are going to take away the explanation column. Solve for a, given the equation 9a+5(3-1)=11, what property is it suppose to be?

see below

Step-by-step explanation:

9a+5(3-a)=11  given

Distribute the 5 using the distributive property

9a +15 -5a = 11

Combine like terms, using simplification

4a +15 =11

Subtract 15 from each side, using the subtraction property of equality

4a+15-15 = 11-15

4a = -4

Divide each side by 4 using the division property of equality

4a/4 = -4/4

a = -1  by simplifying

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
