2+2+2+10+5+5+5+20+20+20+20+20+20=151
20 = 400
If I am correct, 9 plus 7 equals 112.
this is the same as 6x - 2 = 6x - 2! There are an infinite number of possibilities for "x".
144 is the answer.2+3=10 which means 2+3=55*2=107+2=63 7+2=99*7=63now 9+7=? 9+7=1616*9=144
-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
10 plus 10 equals 20 20 divide by 10 equals 2 2 plus 10 equals 12
20 = 400
20. unless this is a trick question.
7+3=10 10*2=20
The answer is 20. In each addition, the individual digits are added together (1+2+3+5+4 = 15)
90.
10
s = 20
20 divided by 4 multiplied by 2 plus 6 equals 16. 20/4 = 5, 5x2 = 10, 10+6 = 16.
61
10 plus 20-2 - 11 plus 3 is equal to 20.
(20 * x) + 3 = 5 20 * x = 2 x = 1/10
