:
let the number = x
Just write an equation for what it says; (the word "is" usually means equal):
:
"four times the sum of twice a number and three is twelve."
4 times (2x + 3) = 12
:
4(2x + 3) = 12
:
"find the number"
:
Mult what's inside the brackets:
8x + 12 = 12
:
you can see here that x has to = 0
8(0) + 12 = 12
