Use substitution to solve the following system of equation s 4y-3= 22 and y=2x-2
Genrish500 [490]

Answer:

x = 33/8

y = 25/4

Step-by-step explanation:

4y - 3 = 22

y = 2x - 2

4y - 3 = 22

4y - 3 - 22 = 0

4y - 25 = 0

4(2x - 2) - 25 = 0

8x - 8 - 25 = 0

8x - 33 = 0

8x = 33

x = 33/8

y = 2x - 2

y = 2(33/8) - 2

y = 33/4 - 2

y = 33/4 - 8/4

y = 25/4
