Use substitution to solve the system of equations. y=x +1.74 4x-2y =4
(3.75,0) (4,4) (3.75,5.5) (5.5,4)

y = 3.75+1.74= 5.49=5.5 =5.5

4(3.75) - 2(5.5) =15 - 11 =4

Step-by-step explanation:

y = x+ 1.74 →  -x + y = 1.74  

(1/2)(4x - 2y = 4) → 2x - y = 2

Add two eq → x=3.74 and y=5.5

The problem says that u need replace but with the process before you can get the result easily.

y = 3.75+1.74= 5.49=5.5 ≠ 0

4(3.75) - 2(0) =15 ≠ 4

y = 4+1.74= 5.74=6 ≠ 4

4(4) - 2(4) =8 ≠ 4

y = 3.75+1.74= 5.49=5.5 =5.5

4(3.75) - 2(5.5) =15 - 11 =4

y = 5.5+1.74= 7.24 ≠ 0

4(5.5) - 2(4) =14 ≠ 4
