<span>multiply the first equation by 5 and 2nd by -7 and you get
35x-30y=-5
-35x+28y=-7
now you can cancel out the x's and you get
-2y=-12
so
y=6
now you can just plug y=6 into one of the original equations and you will see that x turns out to be 5
Hope thats okay</span>
Answer:
x = 3
Step-by-step explanation:
subtract 7 from both sides, then subtract 4x from both sides after
6x +7 = 4x + 13
-7 -7
6x = 4x +6
-4x -4x
2x = 6
divide both sides by 2x
answer x =3
