Question

Solve 7x – 2y = –3
14x + y = 14

Answer 1

answer format like (4 5/7)

Answer 2

x=5/7
y=4

Answer 3

would it come out like (5/7,4) or (4,5/7) or what

Answer 4

Take second equation and solve for y in terms of x.
14x + y = 14
y=14-14x
Now solve by substituting for y in first equation.

Answer 5

(5/7,4)

Answer 6

7x - 2(14-14x) = -3
7x- 28 +28x = -3
35x = = -3 + 28
35x = 25
x=25/35
x=5/7

Answer 7

From y= 14 -14x
y= 14 - 14 (5/7)
y = 14 -10
y=4

x=5/7
y = 4

(x,y)
(5/7, 4)
