Question

substitution method
6x+8y=44
-2x+y=11

Answer 1

y=2x+11

6x+8(2x+11)=44
6x+16x+88=44
22x=-44
x=-2 Substitute this value into one of the equations to find y

-2x+y=11
(-2)(-2)+y=11
4+y=11
y=7

Therefore, x=-2 and y=7

Answer 2

gw2011 thank you could you assist me on this one please
3x+5y=-3
-7x+y=45

Answer 3

y=7x+45

3x+5(7x+45)=-3
3x+35x+225=-3
38x=-228
x=-6 Substitute this value into one of the equations and you get:

-7x+y=45
(-7)(-6)+y=45
42+y=45
y=3

Therefore, x=-6 and y=3
