Question

What is the value of y in the solution to the following system of equations?

5x − 3y = −3
2x − 6y = −6

Answer 1

which method u prefer to used?

Answer 2

Solve both equations for x. Then set the equations equal to each other and solve for y.

Answer 3

ok using elimination method
5x-3y=-3...eq.1
2x-6y=-6...eq.2

we can multiply eq.2 by 2.5 to get
5x-15y=-15...eq..3

now we have
5x-3y=-3
5x-15y=-15

we can take away the two equations to solve for y...

Answer 4

so we have 5x-5x=? , (-3y)-(-15y)=?? and (-3)-(-15)=??
