Question

X-42=-33 what is the solution ?

Answer 1

-42 + x = =33↓

-42 + 42 + x which is also equals to x = -33 + 42↓

-42 + 42 →0;  0 + x → -33 + 42; x  = -33 + 42 ↓

If you add these to from each other -33 + 42 it would equal to "9"

Therefore, "x" = 9 :) 

Answer 2

X = -33 + 42
x = 42 - 33
x = 9
