Solve the following system of equations. Express your answer as an ordered pair in the format (a,b), with no spaces between the
numbers or symbols
2x+7y=-1 and 4x-3y=-19
2 answers:
Multiply the equation 2x+7y=-1 by -2
add to othe equaiton
4x-3y=-19
<u>-4x-14y=2 +</u>
0x-17y=-17
-17y=-17
divide both sides by -17
y=1
sub back
2x+7y=-1
2x+7(1)=-1
2x+7=-1
minus 7 from both sides
2x=-8
divide both sides by 2
x=-4
x=-4
y=1
