Question

Зу = 4х+5
4y = 4х +7

Answer 1

y = 2; x = 1/4

Explanation:

We can solve for y then x using elimination. We can multiply the first equation by -4 to cancel out the xs:

`-1(3y=4x+5)\\\\4y=4x+7\\-3y=-4x-5\\\\y=2\\\\`

Now, we can plug in this 2 for y in any of two equations to find x:

`3(2)=4x+5\\6=4x+5\\1=4x\\1/4=x`
