8x + 14y = 24

Question

6x + 7y = 10

We are suppose to solve for x and y but I don't get the right answer

Answer 1

so why don't you show us what you did? One way is to notice that 14 = 7*2, so if we double the 2nd equation, we get

8x + 14y = 24
12x + 14y = 20

Now if we subtract the equations, the y's cancel out, and we get

-4x = 4
x = -1

Now use that in either equation to get y.

8(-1)+14y = 24
-8+14y = 24
14y = 32
y = 16/7
