Sorry but I'm totally stuck again! Thanks to all who answered my last question :D


Write each of the following without using words: (Btw 'x' doesn't mean multiplied in this case)

5 more than x
seven less than twice x
4 greater than the sum of a and b
three times x plus 4 times y

Thankyou in advance!
 
I think you're looking for something more complicated than it really is :) You just need to use ordinary math symbols.
5 more than x. OK, how do you get 5 more than something? You add 5, right? So that's the answer
x + 5

seven less than twice x
How do you get 7 less than something? - subtract 7. What does twice mean? - multiply by 2
2x - 7

4 greater than the sum of a and b
You know that "the sum of" just means add together
a + b + 4

three times x plus 4 times y
3x + 4y
