The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
7x-5x=8 2x=8 x=4
It is: 12x
142
5x+2x=7x2x + 5x = 7x
x=12
18 + 7x - 12 + 5x = ?18 - 12+ 7x - 5x = ?6 + 2x = ?
5x2+7x = 12 5x2+7x-12 = 0 (5x+12)(x-1) = 0 x = -12/5 or x = 1
(4, -2)
many solutions
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
x=6
7x-5x=8 2x=8 x=4
It is: 12x
The answer to the math problem of 5x plus 7x-4x 6 is -12.
7x + 8 = 5x + 327x = 5x + 242x = 24x = 12hope this helps
