The sum of 26 and twice a number is 312. find the number.

Step-by-step explanation: 26+2c=312

Now we solve for c.

Subtract 26 on both sides giving 2c=286

So c=143

This is the equation in numbers translated (n is a number)

26 + 2n = 312

We have to find what the number (n) is. This means we must isolate n. To do this you must subtract 26 to both sides

26 - 26 + 2n = 312 - 26

0 + 2n = 286

2n = 286

To further isolate n you must divide 2 to both sides

2n/2 =286/2

n = 143

Check:

26 + 143*2 = 312

26 + 286 = 312

312 = 312

The number is 143

Hope this helped!
