Question

write an equation for two times a number added to 6 is 14​

Answer 1

Step-by-step explanation:

Let’s assume this number is ‘n’.

25 is added to 3 times a number. Meaning that you have you have to calculate the 3 times a certain number then add 25. This equals 70.

So it will be (3*n)+25=70

This is the tricky bit. We have to negate the +25 to make it 0. So we -25. We have to do this to both sides.

Now it will be 3*n=70–25

3*n=45

Now 3*n=45

We do not ÷ n because we have to do it both sides. so 3*n÷n=45÷n

3=45÷n which makes sense but it increases an unnecessary step.

We divide 3 and n=15.

3*n÷3=45÷3

n=15
