Solve each system using substitution.

1. 4x = 3y-2; 18 = 3x+y

2. 3x+2y = 23; 1/2x-4 = y

1. 4x = 3 (18-3x) - 2

4x=54-9x-2

4x+9x=52

13x=52

x=4

substitute 4 for x

4 (4) = 3y-2

16=3y-2

16 + 2 = 3y

y=6

So your x would be 4 and y would be 6

to check your solution substitute x and y

4 (4) = 3 (6) - 2

16 = 16

Therefore that's the final answer for number 1.
