The sum of the ages of levi and renee is 89 years. 7 years ago levi's age was 4 times renees age. How old is Levi now?

Let Levi's current age be l. Let Renee's current age be r. Were given two equations:

1. l + r = 89
2. l - 7 = 4(r - 7)

Simplify equation 2 by multiplying through:

1. l + r = 89
2. l - 7 = 4r - 28

Rearrange equation 1 to solve for r and isolate l by subtracting l from each side:

1. r = 89 - l
2. l - 7 = 4r - 28

Now substitute equation (1) into equation (2):
l - 7 = 4(89 - l) - 28
l - 7 = 356 - 4l - 28
l - 7 = 328 - 4l

To solve for l, we type the equation into our search engine and we get:
l = 67
