Answer:

x = 6

y = 21

Step-by-step explanation:

y = 2x + 9

y = 4x - 3

2x + 9 = 4x - 3

• Get the like-terms together:

9 + 3 = 4x - 2x

12 = 2x

• Divide 2x and 12 by 2 (to get x by itself):

12 ÷ 2 = 2x ÷ 2

6 = x OR x = 6

• To find the value of y, we have to substitute x into one of the equations (it doesn't matter which equation you plug x into, if the value of x is correct, both will equal the same number):

y = 2(6) + 9

y = 12 + 9

y = 21

y = 4(6) - 3

y = 24 - 3

y = 21
