3n + 2n = 25 5n = 25 n = 5
28 plus 17 plus 25 plus 54 plus 20 plus 36 is equal to 180.
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.
12 +12 does not equal 25. (It's 24 - test on a calculator if you like!).
If 40 plus x equals 25 then x is equal to -15.

Half a meter is equal to 50 centimeters. 50 centimeters plus 25 centimeters is equal to 75 centimeters.
It doesn't, it should equal 45 again. I am unsure how you got this second answer but it is wrong
25 plus 25 plus 25 plus 20 plus15 plus 6 is equal to 116.
10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5

Technically there are no variables in this equation, as 47 minus 25 is equal to x (22)
