Question

If 5x-7=13, what is the value of 10x-14

Answer 1

10x-14=26

Explanation:

x = 4

10 x 4 = 40

40 - 14 = 26

Answer 2

26

Explanation:

In order to answer this question, we must first find what x equals, so we need to solve for x in the equation 5x - 7 = 13:

5x - 7 = 13

+7 +7

5x = 20

/5 /5

x = 4

Now, we plug in 4 for 'x' in the equation 10x - 14:

10(4) - 14 =

40 - 14 =

26

So, 10(4) - 14 = 26

Hope this helps :)
