Question

The sum of 7 times a number and 3 is 5 please write as an equation (use y for unknown number)

Answer 1

y = 2/7

Explanation:

7y+3 = 5

Subtract 3 on both sides getting 7y = 2

Then divide everything by 7 to isolate the variable y which gets y = 2/7

Therefore the number that multiplies times 7 and adds 3 to get 5 is 2/7.

Hope this helps
