what is 4(j)-7=9

Do you mean simply
4*j - 7 = 9?
If so, add 7 to both sides to get
4*j = 16
Now divide both sides by 4 to get
j = 16/4

Thank thank you so much I came up with the same answer.

4

You're welcome! I'm glad to hear that you came up with the same answer. It's always good to double-check and make sure your calculations are correct.

In this equation, 4j - 7 = 9, the goal is to isolate the variable j on one side of the equation.

To do this, we can add 7 to both sides of the equation to eliminate the -7 on the left side:

4j - 7 + 7 = 9 + 7

Simplifying, we get:

4j = 16

Now, to isolate j, we can divide both sides of the equation by 4:

(4j)/4 = 16/4

Simplifying further:

j = 4

So the solution to the equation is j = 4.
