Add 4 to both sides. Y+4=12x divide both sides by 12 y+4 over 12 which = x switch sides x= y+4 over 12 that’s the answer and I’m 100% sure
Answer:
option 3
Step-by-step explanation:
4x+8<-16
x<-6
4x+8_>-16
x_>-1
(it's more and equal .so the circle has to be shaded and move to the right of -1)
Answer:
Cross Multiply
Step-by-step explanation:
1. Multiply 16 by 9 and you get 144
2. Multiply 5 by x
This is called cross multiplying.
3. Set up the equation. 5x=144
144/5=28.8
x=28.8
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
