Can someone please help explain the steps? I'm having a hard time understanding the other answers to this question. 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.

(3,2)

Step-by-step explanation:

Y=-2x+8 equation 1

y=x-1 equation 2

x-1=-2x+8 substi y of second equation into y of first equation.

3x=9

x=3

solve for y by putting the  x value into either equation

y=x-1

y=3-1

y=2

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
