(-y+4)+ (9y-6) (9y-y) + (4-6) 8y - 2
5y - 4 + 9y - 1y + 15= 5y + 9y - 1y + 15 - 4= (5 + 9 - 1)y + (15 - 4)= 13y + 9
(y - 7)(y - 2)
9y+3=5y+13 4y=10 y=10/4 or 5/2 or 2.5
(y - 2)(y - 7)
(-y+4)+ (9y-6) (9y-y) + (4-6) 8y - 2
The following is the answer.
5y - 4 + 9y - 1y + 15= 5y + 9y - 1y + 15 - 4= (5 + 9 - 1)y + (15 - 4)= 13y + 9
10y = 9y + 4, so y = 4
(y - 7)(y - 2)
9y+3=5y+13 4y=10 y=10/4 or 5/2 or 2.5
9y - 4x
9y subtract 11 equals 7
(y - 2)(y - 7)
13x - 9y - 10
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.
