Answer:
x = 3, y = - 2
Step-by-step explanation:
By substitution method,
4x + y = 10 -------> equation 1.
7x + 2y = 17 -------> equation 2.
From equation 1,
y = 10 - 4x ------> equation 3.
Substitute equation 3 in 2,
7x + 2 ( 10 - 4x ) = 17
7x + 20 - 8x = 17
7x - 8x = 17 - 20
- x = - 3
x = 3
Substitute x = 3 in equation 1,
4 ( 3 ) + y = 10
12 + y = 10
y = 10 - 12
y = - 2
Hence,
x = 3
y = - 2
To solve this you'll plug in the ordered pairs and if the answer is equal then it is the answer.
A: 2 = 3(0) - 2
2 = 0 - 2
2 ≠ -2
B: 1 = 3(1) - 2
1 = 3 - 2
1 = 1
C: 1 = 3(-3) - 2
1 = -9 - 2
1 ≠ -11
D: 0 = 3(2) - 2
0 = 6 - 2
0 ≠ 4
So the answer choice B is the solution to the given equation.
Hope this helps :)
