Question

If 9x+3=30, what is the value of 3x+1

Answer 1

`9x + 3 = 30 \\ \\ 9x = 30 - 3 \\ \\ 9x = 27 \\ \\ x = (27)/(9) \\ \\ x = 3.`

putting x = 3 in 3x + 1

`3x + 1 \\ \\ 3 * 3 + 1 \\ \\ 9 + 1 \\ \\ 10.`

The value of 3x + 1 is 10.

Answer 2

9x + 3 = 30
9x = 27
x = 3

Then 3x + 1 = 3 * 3 + 1 = 10
