7x = 56 To find the solution for x, you should divide both sides of the equation by 7 to get x = 8.
Answer: y 7x when solved mathematically would be equal to y/7x. Answer: If you mean the equation y = 7x, just choose ANY value for "x"; then you can calculate the corresponding value for "y" by multiplying it by 7, in this case.
x2 - 7x = 8 x2 - 7x - 8 = 0Now find two numbers that multiply to equal -8, and add to equal -7.(1) * (-8) = -8(1) + (-8) = -7(x+1)(x-8) = 0 This is the factored form of x2 - 7x = 8You can then solve the equation if necessary, and get:x = -1 or x = +8
Without an equality sign the given terms of an expression can't be classed as an equation and so therefore an answer is not possible.
(7x - 4)(7x + 4).
7x - 56 and that is as far as you can go.
x2 + 7x - 56 cannot be factorised.
5x-9=7x+7
None. 7x - 1 is not equal to 7x - 7.
40 -7x = -16 -7x = -16 -40 -7x = -56 x = 8
56
Divide both sides by -14 x = 4
7x-2
63
7x = 56 To find the solution for x, you should divide both sides of the equation by 7 to get x = 8.
The GCF is 7.
