Solution:7x - 7 = 147x = 14 + 77x = 21x = 21/7x = 3Checking:7(3) - 7 = 1421 - 7 = 1414 = 14
7x + 9 = 51 7x = 42 x = 42/7 = 6
If you mean 7 = 7x-3 then the perpendicular slope is -1/7 and the equation is y = -1/7x
Subtract 2 from both sides of the equation: 7x + 2 - 2 = -19 - 2 7x = -21 Divide both sides of the resulting equation by 7: 7x/7 = -21/7 Solution: x = -3 How much is 5x + 15?
x - 8x = 1 Perform the indicated subtraction on the left side: -7x = 1 Divide each side of the equation by -7 : x = - 1/7

yes
Because 8 does not = 7, there is no solution. You write No Sol. Alternatively if you simplify an equation to x = x, that would be All Solutions (any number substituted for x satisfies the equation) * * * * * Wrong! 8x = 7x DOES have a solution and that is x = 0
3x + 17 + 5x = 7x + 10Combine (add) the 'x'-terms on the left side of the equation:8x + 17 = 7x + 10Subtract 17 from each side:8x = 7x - 7Subtract 7x from each side:x = -7
7x = 56 To find the solution for x, you should divide both sides of the equation by 7 to get x = 8.
To find the equation of a line in standard form (Ax + By = C) that passes through the point (-5, 1) with a slope of 7, we can use the point-slope form first: (y - 1 = 7(x + 5)). Simplifying this gives (y - 1 = 7x + 35) or (y = 7x + 36). Rearranging to standard form results in (-7x + y = 36) or (7x - y = -36). Thus, the standard form of the equation is (7x - y = -36).
It is an equation and the value of x is 1
It's a linear equation in 'x'. The 'solution' of the equation is the number that 'x'must be in order to make it a true statement. A linear equation has exactly onesolution. You can find it like this:-7x - 6 = 29Add 6 to each side:-7x = 35Divide each side by -7 :x = -5
