Question

Ues the diagrams to solve for x and y.

please try to explain too please​

Answer 1

y=4 , x= 12

Explanation:

x + y = 16

8 + y = x

8 + y + y = 16 (simplfy)

8 + 2y = 16 (subtract 8 from each side)

2y = 8 (divide each side by 2)

y = 4

8 + 4 = x

x =12

Answer 2

y=4 , x= 12

Explanation:

This question deals with linear equations so, with this problem, subsitution is the easiest form of solving.

x + y = 16

8 + y = x

Now you know that x = 8 + y, so replace it in the opposing equation.

8 + y + y = 16 (simplfy)

8 + 2y = 16 (subtract 8 from each side)

2y = 8 (divide each side by 2)

y = 4

plug into other formula

8 + 4 = x

x =12
