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:
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
Let Levi's current age be l. Let Renee's current age be r. Were given two equations:
- l + r = 89
- l - 7 = 4(r - 7)
- l + r = 89
- l - 7 = 4r - 28
- r = 89 - l
- l - 7 = 4r - 28
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
