Question

26 less than twice a number is 4. Find each number

Answer 1

15

Explanation:

Let's call the number we try to find "
`x`"

In the problem, we know that "26 is less than twice a number" is the same as "4". So we can write this as an equation:


`2x - 26 = 4`

Now we can solve for x by isolating it on one side of the equation.

First, we isolate "2x" by flipping "-26" to the other side, which will now be "26".


`2x = 4 + 26`

Then we add


`2x = 30`

finally, we isolate the x by dividing each side with 2

2x ÷ 2 = 30 ÷ 2
x = 15
