Answer:
Step-by-step explanation:3x-y=18
y=27
Therefore 3x-(27)=18
3x=18+27..Nb when the 27 is now being added instead of subtracted.
3x=45
3x/3=45/3 Nb the 3 is now being divided instead of being multiplied.
Therefore X=15
Answer: X = 11/5
Step-by-step explanation: Put it in standard form first!!
simplify -2 + 4x = 9 - x
regroup items 4x - 2 = 9 - x
Add two on both sides 4x = 9 - x + 2
simplify 9 - x + 2 to 11 - x
4x = 11 - x
Add x to both sides 4x + x = 11
Simplify 4x + x to 5x
5x = 11
divide both sides by 5
x = 11/5
