Question

What is the solution to the system of equations? Enter your answer as an ordered pair, written as (x, y).
Equation 1: 4/5x - y = -4
Equation 2: y = - 2/5x + 7

Answer 1

Answer:

4x+1/9=5x+7/9

We move all terms to the left:

4x+1/9-(5x+7/9)=0

We add all the numbers together, and all the variables

4x-(+5x+7/9)+1/9=0

We get rid of parentheses

4x-5x-7/9+1/9=0

We multiply all the terms by the denominator

4x*9-5x*9-7+1=0

We add all the numbers together, and all the variables

4x*9-5x*9-6=0

Wy multiply elements

36x-45x-6=0

We add all the numbers together, and all the variables

-9x-6=0

We move all terms containing x to the left, all other terms to the right

-9x=6

x=6/-9

x=-2/3
