Solve this equation!?

5x-2y=14 x 3 15x-6y=42
3x-y=9 x5 15x-5y=45

so take 15x-6y=42 from 15x-5y=45 and we get y=3
now we have to sub in what y stands for.

5x- 6 = 14
5x= 20
x=4

y=3 x=4
and to make sure this works we can try it in 3x-y=9
12-3=9
so yeah, they are the answers

5x - 2y = 14
- 6x + 2y = - 18-----ADD

- x = - 4
x = 4

12 - y = 9
y = 3

x = 4 , y = 3

5x - 2y = 14__________(1)
3x - y = 9____________(2)
from equation (2); y = 3x - 9_______(3)
substitute equation (3) into equation (1);
5x - 2(3x - 9) = 14
5x - 6x + 18 = 14
-x = 14 - 18
-x = -4
x = 4

3x - y = 9
y = 3x - 9
substituting in 5x - 2y = 14
5x - 2(3x - 9) = 14
5x - 6x + 18 = 14
-x = -4
x = 4
y = 3(4) - 9
y = 3

5x - 2y = 14 (solve by using substitution)
3x - y = 9

3x - y = 9
y = 3x - 9

5x - 2y = 14
5x - 2(3x - 9) = 14
5x - 6x + 18 = 14
-x = 14 - 18
-x = -4
x = -4/-1
x = 4

5x - 2y = 14
5(4) - 2y = 14
2y = 20 - 14
y = 6/2
y = 3

∴ x = 4 , y = 3

y= 3x-9

5x - 2(3x-9) = 14
5x - 6x +18 = 14
-x = -4
x=4
y= 12-9
y = 3

Multiply the bottom equation by 2
5x-2y=14
6x-2y=18

Now subtract the bottom equation from the first
-x=-4
Multiply by -1
x=4

Plug that in for x in one of the two equations
3*4-y=9
12-y=9
-y=-3
y=3
