12%=(3+10%*x)/(20+x)
x=30
add 30 pounds of the second alloy
(10x 5 - 3x 6)
(50x - 18x)
(f-g) = 32x
Answer:

Step-by-step explanation:
First, you need to combine like terms in order to begin simplifying. This is done by subtracting 2x from 6x. Also, add 7 to 23.
6x + 10 - 2x = 7 + 23
4x + 10 = 7 + 23
4x + 10 = 30
Now, you have a two-step equation. Subtract 10 from both sides, and then divide by 4.
4x + 10 = 30
4x = 20
x = 5 is the final answer.
