Mike gave Danny 4 more marbles than he already had. He now has 100 marbles. How many marbles did Mike give to Danny?
I don't no the answer
x+x+4=100
2x+4=100
2x=96
x=48
To find out how many marbles Mike gave to Danny, we can set up an equation based on the given information.
Let's say Danny originally had "x" marbles. Mike then gave Danny 4 more marbles, so Danny's total number of marbles became:
x + 4
According to the problem, Danny now has 100 marbles. So we have the equation:
x + 4 = 100
To solve for x, we need to isolate it on one side of the equation. To do so, we can subtract 4 from both sides:
x + 4 - 4 = 100 - 4
x = 96
Therefore, Danny originally had 96 marbles. To find out how many marbles Mike gave to Danny, we can subtract Danny's original number of marbles from the total number he currently has:
100 - 96 = 4
So, Mike gave Danny 4 marbles.
