Question

a number decreased by seven and then divided by five is thirteen. What is the number? write an equation to solve

Answer 1

13 x 5 = 65

65 + 7 = 72

Step-by-step explanation:

First set up the equation with ‘x’ being the unknown number. Then set up an inequality where the actions done to x equal 13.

`(x-7)/5=13`

Now solve for x

First multiple both sides by 5 That gives us

`x-7=65`

Now add seven to both sides to isolate and solve for x

`\bold{x=72}`
