4x-8=2x+14
subtract 2x on both sides and add 8 on both sides so x=11
Answer: 1= X = 8
2= X = 6
3= X = 7
4= X= 9/13 or X= 0.692307
Step-by-step explanation: hope this helps pls mark me brainliest
So, u would start by expanding the bracket and ignoring the 2 at the moment.
(x+9)(x+9)= x^2-18x+81(using the foil method!
Then u would put 2 at the front to get:
2(x^2+18x+81)
= 2x^2+36x+162
4 fries + 6 cheeseburgers = $52
3 fries + 2 cheeseburgers = $24
9 fries + 6 cheeseburgers = $24×3
= $72
$72-$52=$20
5 fries = $20
1 fries = $20÷5
= $4
1 cheeseburger = [$24 - (3×$4)]÷2
= $6
