The two unknown variable in the two given equations are "x" and "y".
3y + 3x = 24
Dividing both sides by 3 we get
y + x = 8
x = 8 - y
Putting the value of y in the second equation we get
6y + 3x = 39
Dividing both sides by 3 we get
2y + x = 13
2y + 8 - y = 13
y = 13 - 8
= 5
Putting the value of y in the first equation we get
y + x = 8
5 + x = 8
x = 8 - 5
x = 3
So the value of x is 3 and the value of y is 5. I hope the procedure is clear enough for you to understand.

Answer:
45
Step-by-step explanation:
6/2 = 3
42+3 = 45
The formula for the volume of a cube whose sides are s inches longs is volume = s^3 cu. in which is A on the choice you provided. We all know that 3 is for cube and the s^3 in the formula saying that s^3 is s cube, we will just include the inches and the cube o the formula which will be the choice A.
