Question

if 3 is detucted from 3 times a certain number the result is 36 find the number

Answer 1

Answer:

13

Step-by-step explanation:

let the number be x

so,

$(3 \times x) - 3 = 36 \\ \\ 3x - 3 = 36 \\ \\ 3x = 36 +3 \\ \\ 3x = 39 \\ \\ x = 39 \div 3 \\ \\ x = 13$

Answer 2

Answer:

13

Step-by-step explanation:

Lets write this as an equation to help:

3x-3 = 36

Now bring the -3 on the other side:

3x = 36+3

3x = 39

Now we just divide both sides by 3:

x = 13

To factcheck we can put 3 back in the equation:

3(13) - 3

39 - 3

36
