Question

I thought of a number. 7 times the number decreased by 13 equals 5 times the number increased by 5. What was my number?

Answer 1

Convert the word problem into equation

Let the number be x

By the problem

7x-13=5x-5

Transport the 5x to lhs and -13 to rhs

7x-5x=13-5

2x=8

x=8/2

x=4

Therefore the number is 4
