Answer:
6
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.
3x=6
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
