Question

solve the system of linear equations
4x-3y=17
5x+4y=60

Answer 1

Same as the previous one i helped you with but you need to multiply both lines by 2 different numbers the first line being 4 and 2nd line being -3. so you get
16x-12y=68
-15x+12y=-180

and you get x=-112

then plug -112 back into one of the 2 (i will do the first line) and you get

16(-112)-12y=68
-1792-12y=68
-12y=1860
y=-155

then you can check by plugging both values in:

16(-112)-12(-155)=68
-15(-112)+12(-155)=-180
