Question

Solve the system of equations using the addition method.

5x - 2y = 12
3x + 2y = 36

Show your steps, and explain how you verify the solution.

Answer 1

A) 5x - 2y = 12

B) 3x + 2y = 36 Adding both equations eliminates "y"

8x = 48

x = 6 Putting x=6 into equation B we get

3*6 + 2y = 36

2y = 18

y = 9

Explanation:

Answer 2

5x-2y=12 eq1

3x+2y=36 eq2

8x=48

x=6

X iS 6

substitute X S6 in equation 2

3 into 6 + 2 Y is equal to 36

18 + 2 Y is equal to 36

Y is equal to 9
