Question Description

I need an explanation for this Algebra question to help me study.

1. Use substitution to solve the system of equations given below.   

Y= -2/3X – 5       2x + 3y = 5.


2.Use substitution to solve the system of equations given below.

x= 1/2y – 4       4y – 6x = 12.


3. Use substitution to solve the system of equations given below

y = 2x   5x – y = -24.

4.

Use substitution to solve the system of equations given below.

8x – 4y = 16     

2x – y = 4.
