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
7x + 7 = 7(x + 1)
x2+7x x(x+7)
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.
It is 7+8x simplified
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)
