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 2, subtract 3 and multiply the result by 4”

8x - 12

Step-by-step explanation:

Let the number be x

multiply by 2

= x * 2 = 2x

Subtract 3 ;

2x-3

Multiply result by 4

=

4(2x -3) = 8x-12

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

a)(x-2)^2+(y-1)^2=9
