Consider the following pair of equations: y = −2x + 8 y = x − 1 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.

{y = -2x + 8, y = x - 1} = (3, 2) OR x:3 and y:2

Step-by-step explanation:

1. We are given the value of y in terms of x (an equation where the variable y is isolated).

2. Since y = x - 1, plug this into the first equation for y to start solving. (this is the value of y in terms of x)

3. x - 1 = - 2x + 8

4. Substitute "x" in for "y" in either equation but since the second is easier we will do that one.

Hope this helps! If you have any questions regarding concepts, please reach out!

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
