Question

Solve the following system using the substitution method.

10x + y = -1
5x + 2y = 16

Answer 1

okay take y seperate from 1st equation and put it in 2nd
y=-1-10x

Answer 2

putting it in 2nd equtaion
5x+2(-1-10x)=16

Answer 3

5x-2-20x=16
-15x=18
x=-18/15
x=-6/5

Answer 4

now put x in y=-1-10x
y=-1-10(-6/5)
y=-1+60/5
y=-1+12
y=11, x=-6/5

Answer 5

ok, thanks again khurram!
