Answer:

Step-by-step explanation:

If 10 + 5x is 12 more than 8, what is the value of 3x? We can represent this with the equation below.

10+5x = 12+8.

Simplifying this gives us 10+5x = 20, then 5x = 10, then x = 2.

If x = 2, then 3x = 6.

Answer:

3x=6

Step-by-step explanation:

10 + 5x =8+12

10 +5x = 20

Subtract 10 from each side

10-10+5x=20-10

5x= 10

Divide by 5

5x/5 = 10/5

x = 2

We want 3x

3(2) = 6

3x=6
