The answer to the math problem -3 7x plus 7 is x equals 1/3.

Either: (7x + 4)(x + 4) = 7x2 + 32x + 16 or: (7x - 4)(x - 4) = 7x2 - 32x + 16

4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1

Here is the work for that problem. 7x+6= 41 7x=41-6 (subtracting 6 from both sides) 7x=35 x=5

-46 = 3x + 7x

-46 = 3x + 7x

7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8

7x + 5 = 68 subtract 5 from both sides 7x = 63 divide both sides by 7 x = 9

simple. Set out the problem clearly: -9 + 7x = -37. Move the singular number over the equals sign, which makes itself opposite, in this case, the 9 is negative, and when moved over the equals sign, becomes positive. 7x= -37+9 7x= -28 x= -28/7 x = -4

13x

It is 9x

x=6

-7x + 5 = -9 -7x = -14 7x = 14 x = 2
