Question

2x less 2 times the sum of 2x and 1 is equal to the sum of 2 and 5

Answer 1

Hi Bernard, I think I can help you with this problem. Sounds like you need to write this sentence in an equation and solve for the variable x.

Can you think of which functions the keywords "less," "times" and "sum" stand for? ...if you answered subtraction, multiply, and add, you're correct!

Here is the equation I came up with:

2x - 2(2x - 1) = 7

Distribute the -2... 2x - 4x + 2 = 7

Combine like terms... -2x = 5

Divide both sides by -2... x = -5/2

I hope this helps!
