Use algebra. 12x+30=15x-20. Add 20 to both sides. 12x+50=15x. Subtract 12x from both sides. 50=3x. Divide both sides by 3. 16.666...=x
x + 10
x + 5
sixty is equal to 10 plus 50, and as 10 equals 50, and 50 equals 79, then it would be fair to assume that 60 equals 50 plus 79, which is 129.

-50 plus 50 equals 0
x + 5; provided, of course, that x ≠ -10.
sixty is equal to 10 plus 50, and as 10 equals 50, and 50 equals 79, then it would be fair to assume that 60 equals 50 plus 79, which is 129.
The answer is 983.
2,500 Or; 50+50=100
To solve this one, subtract 50 from 180 and you'll have your answer.
