Answer:
34
Step-by-step explanation:
7(5-2y) + (3y-5) and y=4.
Dont stress out luv so what you do is replace y with 4 like this:
7(5-2x4) + (3x4-5)
= (35-8) + (12-5)
=27+7
=34
When you have a number outside the bracket like 7(5-2x4), the number outside the bracket which in this is 7, you times it by the numbers inside.
So:
7(5-2x4) so you need to first do 5-2=3 then times it by 7, 7x3=21, then you do 7x4 which is 28.
