Miguel and Danny have $129 altogether. Danny has $27 less than Miguel. How much money does Miguel have?

M + M-27 = 129

now solve as usual.

answer: 78

I used basic algebra to solve:

let m = miguel's amount
m - 27 represents danny's amount, because he has 27 less than miguel
129 is the total amount, so miguel's amount plus danny's amount is a sum of 129

129 = m + (m - 27)

I plugged in miguel's and danny's amounts into the above equation, below I solve:
129 + 27 = 2m
156 = 2m
m = 78
miguel's amount is 78

To find out how much money Miguel has, we need to use algebra to solve for the variable representing Miguel's amount of money.

Let's assume the amount of money Miguel has is "x" dollars.
According to the given information, Danny has $27 less than Miguel, which can be represented as "x - 27".

We know that Miguel and Danny have a total of $129, so we can write the equation:

x + (x - 27) = 129

To solve this equation, we can simplify it:

2x - 27 = 129

Next, we can isolate the variable by adding 27 to both sides:

2x = 129 + 27
2x = 156

Finally, dividing both sides by 2 will give us the value of x:

x = 156 / 2
x = 78

Therefore, Miguel has $78.
