Answer 1

A) 5x -2y = 18
B) x +6y =10

Multiply equation "A" by 3 and add it to equation "B"
A) 15x -6y = 54
B) x + 6y = 10

That should help you out.

Answer 2

@wolf1728 hi i need some help i did that and got x=49


this is what i did

3(15-6y=54)3
45-18y=162
y=-13/2

so then i put that in

x+6(-13/2)=10
and then got
x=49

Answer 6

Wolf already multiplied equation A by 3 for you.

All you need to do is add the two equations now and solve for x.

15x -6y = 54
x + 6y = 10

Answer 13

does anything change on how i solve this problem b/c it begins with 2x and x?

@TheSmartOne

Answer 15

you can multiply the second equation by 2 and eliminate x

Answer 16

not by negative 2? @TheSmartOne

Answer 17

if you do it by 2, you have to subtract the equations

if you do it by -2, you have to add the equations
