Graph the system of equations below on a piece of paper. What is the solution? TW y=x-1 y=-2x+5

d1i1m1o1n [39]

<h2>Given↷</h2>

A system of equations

y= x-1
y= -2x+5

The solution to the system of equations

<h2>Answer↷</h2>

(2,1)

<h2>Solution↷</h2>

y = x -1 _ _ _ _ _ _(1)

y=-2x+5_ _ _ _ _ _(2)

subtracting equation 2 from equation 1,

we get,

x -1 = y

-(-2x +5 = y)

__________

3x -6 = 0

3x = 6

x = 6/3

x = 2

___________

Plugging the value of x in equation 1,

y= 2-1

y= 1

hence, the solution of this system of equation is (2,1)
