Answer:
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
