Question

X+3y=15 -8x+3y=-12 how can you order a ladder

Answer 1

I dunno wat lader yo talking about, go to home depot or something

I can solve th system of equaitons though


multiply second equation by -1 and add to toerh equaiton

8x-3y=12
x+3y=15 +
9x+0y=27

9x=27
divide both sides by9
x=3
sub back

x+3y=15
3+3y=15
minus 3
3y=12
divide 3
y=4

(3,4) is solution
