DO YOU KNOW HOW TO MULTIPLY?
OpenStudy (nincompoop):
ONCE YOU SOLVED FOR Y, YOU CAN USE THAT VALUE INTO ONE OF THE EQUATIONS THEN SOLVE FOR X

@TP11 why does people say someone should know something: you dont know my grade/age/etc and people cant always be like you and know everything you dont know things either is that wrong to ask for help.. is that ok to ask for help if you dont want to help me LEAVE instead of bothering me

Multiply the second equation by 2 and then subtract the two equation.
Eqn.1 -> 8x+3y=36
Eqn.2 -> 2*(4x+7y=40) = 8x+14y=80
8x+14y=80
- 8x+3y=36
=0x+11y=44
y=4
Substitute y into one of the equations, it doesn't matter which.
8x+3(4)=36
8x=36-12
x=24/8 -> x=3
`x=3 and y=4`
