Question

Four times a certain number is the same as the number increased by 78. Find the number.

The number is ____. (Give only the value of the number as your answer.)

Answer 1

4x=x+78

Solve for x

Answer 2

4*x = y
y = x+78

4*x = x+78
x= 26

Answer 3

4x-x=78m so, 3x=78, x=78/3 x= 26

Answer 4

Let's write it out another way just to be sure!
\[\large 4x=x+78\]\[\large 4x-x=78\]\[\large 3x=78\]\[\large \frac{3x}{3}=\frac{78}{3}\]\[\large x=\frac{78}{3}\]\[\large \frac{78}{3}=26\]\[\large x=26\]
