i only need help on these two:

*2/3y=10+4x

5x=1/3y-8

*5x=4y-30

2x+3y=-12

DIRECTIONS:use linear combinations to solve the system of linear equations.. thanks :)

I suggest you study the two answers given before and proceed with solving the remainder. This way, you will have no problems to face your exams.

One of the answers is:

Have you tried substitution?

In the second problem,

x = -6 - (3/2)y

-30 -(15/2)y = 4y -30

y = 0

5x = -30

x = -6
