Question

Solve the following equation then place the correct number in the box provided 7x/15 - 1 = 22

Answer 1

Hello from MrBillDoesMath!

Answer:

345/7

Discussion:

7x/15 - 1 =22 => add 1 to bot sides

7x/15 = 22 + 1 = 23 => multiply both sides by 15/7

(15/7)(7/15)x = (15/7)* 23 => as (15/7)(7/15) = 1

x = 15*23/7 => as 15*23 = 345

x = 345/7

Thank you,

Answer 2

x = 345/7

Explanation:

7x/15 - 1 = 22

Add 1 to each side

7x/15 - 1 +1= 22+1

7x/15 = 23

Multiply each side by 15/7 to isolate x

15/7 * 7/15 x = 23 *15/7

x = 345/7
