Question

What is the value of x in the equation 3x - y = 18, when y= 27?
O 5
O 7
O45
O 63

Answer 1

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
