Question

write an equation to represent the problem. When 3 is subtracted from two times a number, the result is 17

Answer 1

2x -3 = 17

When it says two times a number, we use a variable to replace the "number" since we do not know what it is. So, 2x. 3 is being subtracted from 2x, so 2x-3. Then, it says the result is 17, so 2x-3=17
