You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions than posting the question on WA. I could tell you the answer but how can you be sure that I did not make a mistake? Or that I am not messing about?
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 - 40 = 10 + 0
10 + x = 50x = 40

thirty plus 50 equals 80 it is quite simple. all you do is you just add 3 and 5 then add on the zero.

50 - 40 = 10 + 0
10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
18 + 10 + 20 + 30 + 15 + 50= 143
"10 + 50 = 80" is an incorrect equation.
6x + 10 + 4x = 5010x + 10 = 5010x = 40x = 4
1 plus 2 plus 3 plus 4 equal 10. 10 times 5 equals 50.

10 + x = 50x = 40
10 is.
Multiply by 10...
5x+10=60 5x=50 5/5=1 50/5=10 So the answer is 10
