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.
