Question

The difference between six times a number and 7 is equal to five times the sum of the number and 4. Find the number.

Answer 1

The difference (subtraction) of 6 times a number (x represents number) and 7. This gives us 6x-7. That is equal to five times (multiplication) the sum (addition) of the number, x, and 4. This gives you = 5(x+4) and combined gives us B, 6x-7=5(x+4).
