(-y+4)+ (9y-6) (9y-y) + (4-6) 8y - 2
The variables have no known values and as an expression it is: 5x+9y+5
-5y2+3x+2y
That is the most simplifiable version of this equation.
I have no idea what a recoprocal is, but the reciprocal of 2 is 0.5 or 1/2.
9y - 4x
(-y+4)+ (9y-6) (9y-y) + (4-6) 8y - 2
The variables have no known values and as an expression it is: 5x+9y+5
To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.
Y-8x plus 9y equals 10y-8x.
9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
-9y + 8 = -91-9y = -91 -8-9y = -99y = -99-----9y = 11-99/-9 = 11 because -9X11 = -99
If: 9y-20y = 25 Then: y = -25/11
-5y2+3x+2y
That is the most simplifiable version of this equation.
