Answer:

C. 55

Explanation:

Subtract 2 on both sides: 0,4x+2-2=24-2=22

Divide 0.4 from 22 to solve for x: 22/0.4=55

Answer:

C.) 55

Explanation:

If we subtract by 2 on both sides, we would get that 0.4x = 22, and since .4 is 4/10, we can multiply by 10/4 on both sides to make one side x. 10/4 times 4/10 is equal to 1, and 10/4 * 22 is 55. We get that 1 * x = 55, and 1 * x is the same as x, so x = 55.
