6x - 7
16
9x-5x-2x = -4 2x = -4 x = -2
It is equal to -18x^2 +9x
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
X = 7 9x - 2x = 49
the new problem would be 9(7)-2(7) when you substitute 7 for x.The answer is 63-14= 49 So your answer is 49(:
It's 9 x 7 minus 2 x 7. So its 63 - 14.
6x - 7
The expression simplifies to: -7x-4
It can be simplified to: 9y-2x
2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x
16
2x + 9x simplified would be 11x
2x + 24 = 9x - 39= 2x + 63 = 9x= 63 = 7x= x = 9
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
9x-5x-2x = -4 2x = -4 x = -2
