Answer:
y > 
Step-by-step explanation:
Given
5y + 3 > - 7y + 13 ( add 7y to both sides )
12y + 3 > 13 ( subtract 3 from both sides )
12y > 10 ( divide both sides by 12 )
y >
, that is
y > 
Answer: y=4x-9
explanation: move the -4x over to the other side and it becomes positive 4x and -9 stays the same.
Answer:
-12x+16=y
Step-by-step explanation:
Subtract 3 from 11: 8-0.5y=6x
Move 0.5y to the right side: 8=6x+0.5y
Move 6x to the left side: -6x+8=0.5y
Divide both sides by 0.5: -12x+16=y
Answer:
x + y = 11
Step-by-step explanation:
You would need to substitute the numbers into the expression.
Evaluate means that we need to work out what the answer would be.
x + y is equivalent to 9 - - 2.
- - is equivalent to +.
Therefore you would do 9 + 2, which equals 11.
Hope this helps :)
