35xy/56x
let's split this into integers and variables to make it easier for you.
35/56
you factor out 7 from both numerator and denominator
7*5/7*8
you have the right to cancel any like factors both in the numerator and in the denominator ( factor mean something times something-not + or - )
so, the 7 is canceled; top and bottom
5/8
Now, same with variables
xy/x
x canceled; top and bottom
y
Now, that is how
35xy/56x
can be
5y/8
40
It equals x+5y simplified
-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
6y + 5y = -66 11y = -66 (-66/11 = y) y = -6

40
It equals x+5y simplified
y/5 = y/6+9 Multiply all terms by 30 to eliminate the fractions 6y = 5y+ 270 Subtract 5y from both sides 6y-5y = 270 y = 270
5y + 24 = 29 5y = 5 (subtract 24 from both sides) y = 1 (divide by 5)
-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
-8x-5y-45 is not an equation. An equation requires an equal sign in there somewhere. If you meant -8x-5y=45, then there are many ways to rewrite it, such as -(8x+5y)=45, or 8x+5y=-45, or 8x=-(45+5y), to name three. If you meant -8x-5y=-45, then you're probably looking for 8x+5y=45.
no, 4x-3y=11x 3x-5y doesn't equal -11
6y + 5y = -66 11y = -66 (-66/11 = y) y = -6
-3
The expression -5y + 6 is a combination of a variable (y) and constants (-5 and 6) connected by addition and subtraction operations. To find the answer, you would need a specific value for the variable y. Without knowing the value of y, the expression -5y + 6 cannot be simplified further.
x/5y + 2x/3y = 3x/15y + 10x/15y = 13x/15y
