and

x4 when x =3
pls do step by step

Answer 1

x=1

Step-by-step explanation: 9x+7=16

Subtract 7 from both sides.

9x=16−7

Subtract 7 from 16 to get 9.

9x=9

Divide both sides by 9.

​Divide 9 by 9 to get 1.

x=1

Answer 2

34

Explanation:

9x+7 when x=3

Plug 3 into the equation for the variable x

So, it would be 9(3)+7

Multiply 9×3 together to get 27

Finally, add 27 and 7 together

The answer should be 34
