Solve the simultaneous equations -x + 5y = -7 x + y = – 5 x = 1 y= 0

vodomira [7]

y= -5-x

-x + 5(-5-x) = -7

-x -25-5x =-7

-x-5x = 25 -7

-6x= 18

x = -3

-3 +y = -5

y= -5 +3

=-2

-(-3) + 5(-2)

3 - 10 = -7

Multiply by 4 on both sides. This results into:

24 = a + 8

If 8 is substracted in both sides then a would be:

16 = a

Margarita [4]

your question: 

A pair of equations is shown below:

y = 7x − 9

y = 3x − 1

Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points) YOU HAVE ALREADY ANSWERED

Part B: What is the solution to the pair of equations? (4 points)

answer: 

the solution to the pair of equations would be

(2,5)

how do we get this?
