y=−9/2x+10
step-by-step explanation:
let's solve for y.
0−9x−2y=−20
step 1: add 9x to both sides.
−9x−2y+9x=−20+9x
−2y=9x−20
step 2: divide both sides by -2.
−2y
−2
=
9x−20
y=
−9
2
x+10
set each factor equal to 0
4x-3 = 0
2x-1 = 0
solve for x.
4x-3=0
4x=3
x= 3/4
2x-1= 0
2x= 1
x= 1/2
eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
i think it might be a but you might want a second opinion
