5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
9y - 4x
I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43
2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y which can be simplified to 6(x + 2y)
Y-8x plus 9y equals 10y-8x.
The variables have no known values and as an expression it is: 5x+9y+5
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
7(5x + 9y)
Slope-intercept form is y = mx + b5x + 9y = -36Subtract 5x from each side:9y = -5x - 36Divide everything by 9:y = -5/9x - 4
x = 2, y = 1
It is 12x + 11y + 9.
13x - 9y - 10
Splitting the equation up into the two variables: x + 4x = 5x -7y + -2y = -9y Therefore, the simplified version is: 5x - 9y
5x + 9y-3 is a trinomial term true of false
5x(6x + 9y + 2)
It is an algebraic expression that can be simplified to: 5x+9y+5
5x + 6y + 3y - 2x you have to add like terms. add the y terms and then the x terms 9y + 3x this is your answer
