Question

The sum of seven times a number, and 2, is equal to six times the number.

Answer 1

Sum means addition. Times means multiplication, and "is" means an equality, or equals. We use a variable to represent the unknown number.

So 7x+7 is the sum of seven times a number and 7. 6x means six times the number. 6x is 7x+7, leading to the final answer 7x+7=6x.
