Question

2x+4y=-6
x-3y=-7

Answer 1

what do you need to do?

Answer 2

Substitution

Answer 3

okay here we go :)

Answer 4

x=3y-7

2(3y-7)+4y=-6
-14+6y+4y=-6
10y=8
y=0.8

x=3(0.8)-7
x=2.4-7
x=-4.6

Answer 5

Thanks. I'm going to take a look at this so I can see what you did

Answer 6

ok:
2x+4y=-6
2x=-6-4y ( by transposing 4y to RHS )
2x/2=(-6-4y)/2
x=(-6-4y)/2

NOW PUTTING THE VALUE OF x in the equation no. 2 :
x-3y=-7
(-6-4y)/2-3y=-7
(-6-4y-6y)/2=-7
-12y-4=-14
transposing -4 to RHS
-12y=-14+4
-12y=-10
y=-10/-12
y=5/6
