Question

Solve the system.
y = 2 - x and y = 4x + 7
A. (1, 1)
B. (1, 3)
C. (-1, 3)
D. (-1, 1)
E. no solution

Answer 1

C(-1,3)

Answer 2

x=-1,y=3 so C(-1,3 ) is correct

Answer 3

Eq. One
y=2-x
x+y=2
Eq. Two
y=4x+7
4x-y=-7
Now Solving two eq.

Now put value of X in eq one
y=2-x
y=2-(-1)
y=2+1
Y=3
So the answer is (-1,3)
