Let f(x) = 2x - 3. If f(x) = 15, what is x?

9=x

Step-by-step explanation:

In explanation

Step-by-step explanation:

Using f(x), we can work backwards to find x:

15 = 2x-3

18=2x

x=9

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
