7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
4x - 7 = 5 + 7x x = -4
7x + 6 = -18 7x = -24 x = -24/7 x = -3.428571 recurring (that is, -3.428571428571...)
7(x + 4)
7x + 28
In 7x+7, x is a variable.
7x + 7 = 7(x + 1)
7x+7=28x 28x-7x=7 21x=7 x=3
(7x + 7)(x + 2) = 7x2 + 21x + 14
The answer to the math problem -3 7x plus 7 is x equals 1/3.
7x+8-x-7 6x+1
-7(x + 6) = -7x - 42
x=(-9/7) 7x+12=3 7x=(-9) x=(-9/7)
7x + 29 = 36 7x + 29 - 29 = 36 - 29 7x = 7 7x/7 = 7/7 x = 1
7x + 8 = 36 Therefore, 7x = 28 x = 28/7 x = 4
7x2 + 7x - 14 = 7(x2 + x - 2) = 7(x + 2)(x - 1)
7x + 8 = 84 7x = 84 - 8 x = 76/7 x = 10.8571
