Is (4,−1) the solution of the system of equations shown below?
3x+2y=10
−2x+y=−7
1 answer:
Answer:
No, no it is not.
Step-by-step explanation:
First step : Solve for y in − 2 x + y = − 7.
y = 2 x − 7
Second step : Substitute y = 2 x - 7 into 3 x + 2 y = 10.
7 x − 14 = 10
Solve for x in 7 x - 14 = 10.
x = 24 / 7
Substitute x = 24 / 7 into y = 2 x - 7.
- 1 / 7
That means your answer is.
x = 24 / 7
y = − 1 / 7

Answer:
y = -2/3 x + 5/3
Step-by-step explanation:
y = mx + b
y = -2/3 x + b
1 = -2/3 × 1 + b
3/3 + 2/3 = b
b = 5/3
y = -2/3 x + 5/3
