How do I solve x+4y=22<br> -x+5y=23
xxTIMURxx [149]
{ x + 4y = 22     ( + x - x = 0 )
{ - x + 5y = 23

4y + 5y = 22 + 23
9y = 45

What are the domain restrictions of a + 1 / a^2-5a-36?
velikii [3]
All real numbers except -4 and 9.    

The domain of an expression is the range of all values for which the expression is defined. Looking at the expression, it will legal everywhere except when a^2 - 5a - 36 is equal to 0. Since that's a quadratic equation, we can use the quadratic formula to find where its value is 0, giving -4 and 9.    

Therefore the domain of the expression is, All real numbers except -4 and 9.
