1/5 + 2/5 = 3/5
In addition the denominators stay the same (If they are alike). You just add the numerators.
Ex: 6/8 + 2/8 = 8/8 or 1.
x=8
2y + 7x + y-1?
467
n = 28
3 + 542 = 545 - 6 = 539.
divide both sides by 2
x=8
-7
The letter X in the equation 14 plus X21 would be 2.5. this is a math problem.
There can be no solution because there is just an expression - no equation nor inequality.
well we can't simiply solve that problem. we must no what y= to solve this. So u can only simpify ok combine like terms. 2y plus 9y is 11y. your answer is 11y+9
Σxievaluated for [ 0 < i < 11 ]. (That's just a neater way to write the problem. It doesn't help you solve it ...you still have to know how to add.)
