First answer 3l - 5 is how to represent his age
One number is x
other number is 3x-10
x + 3x - 10 = 50
4x = 50 + 10
4x = 60
x = 60/4
x = 15 ← one number
the other number = 3x - 10 = 3*15 - 10 = 35
Step-by-step explanation:
3( x +1) = 5 (x - 2) + 7
3x + 3 = 5x - 10 + 7
5x - 3x = 3 + 10 - 7
2x = 13 - 7
2x = 6
Therefore x = 3
The answer to the following question is 61
7x+1000+x=89000
7x+x+1000-1000=89000-1000
8x=88000
8x/8=88000/8
x=$11000
