- 10 + x = 3
Add 10 to both sides: 0 + x = 3 + 10 or x = 13
You add 10 to -7 to get 3.
you need to add 3/10 to 7/10 to get 10/10 or 1.
4
if ya add 10 u get zero, so add 13 n u get 3......which grade are u in btw :P
You need to add 18 to negative 8 to get 10.
you need to add 10
your expression is this... x + -10 = 2 x = 12 You need a 12 to add to -10 to get 2
-10
-10 + 20 = 10 because you need 10 to get 0 and 10 more to get +10
if you mean 9/10 + 3/5 then multiply 3/5's numerator and denominator to get 6/10, which you can add to 9/10 to get 15/10, or 3/2. 1 1/2 if you need mixed numbers.
15-10 = 5
10 - (-9) = 19
