Question

Write and describe the four steps for using the linear combination method to solve a system of equations, use complete sentences. 1. Arrange. 2. multiply if needed. 3. Add or subtract and solve. 4. Find the other variable. ALWAYS CHECK Solve this system using the linear combination method. Show your work and explain each step. 2x + y = 8 x − y = 4

Answer 1

Explanation:

2x+y=8x-y=4

First solve take all x variable to one side and all the y on one

y+y=8x-2x=4

2y=6x=4

Solve for x solve for y

6x=4 2y=4

x=4÷6 y=2

x=4/6
