use substitution
6x+21 = 2x+37
4x = 16
x = 4
go back to either equation
y = 2(4) + 37
y = 45
how did you get x = 8 ?
y=2x+37
y=6x+21
How do I solve this? I know x is 8 but I plugged in y twice and got two different answers.
4 answers
nvm i got it
x= 4 and y=45
x= 4 and y=45
oh, I tried to use elimination, I subtracted the 2nd equation form the 1st
