If I was asked to think of a number and multiply it by 2, I could write this algebraically as 2x.
Write the following algebraically, using x as your unknown.
"I think of a number, multiply it by 3, add 4 and square the result."

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

−2

y=

−9

2

x+10

answer: the first one
