Question

When a number, x, is multiplied by 4, then subtracted from 68, the result obtained is the same as three times the sum of x and 4. Find x.​

Answer 1

Answer:

x = 80

Step-by-step explanation:

Let's start off with making an equation to help us solve this problem.

x * 4 - 68 = 3 ( x + 4 )

Simplify the equation.

4x - 68 = 3x + 12

Next, we have to switch the terms ( x ) to one side and the numbers to to other.

-68 - 12 = 3x - 4x

Simplify the equation.

-80 = -x

In order to find the value of x, we have to multiply each side by -1 to cancel out the negatives.

80 = x

The value of x is 80.
