Answer:

(7, 1/2)

Step-by-step explanation:

Multiply second equation by 2 and subtract.

3x - 4y = 19

- (4x - 4y = 26)

You get -x = -7

x = 7

Substitute x into any equation.

3(7) - 4y = 19

21 - 4y = 19

-4y = -2

y = 1/2

These require you solve for y. Do that by subtracting the x-term, then dividing by the y-coefficient.

5. 3y = 7x -9
y = (7/3)x -3

6. 6y = -2x -3
y = (-2/6)x -3/6
y = (-1/3)x -1/2

7. 8y = 2x + 12
y = (1/4)x +3/2
