How do you do this equation 7x-7 equals 14?
Solution:7x - 7 = 147x = 14 + 77x = 21x = 21/7x = 3Checking:7(3) - 7 = 1421 - 7 = 1414 = 14
What is the solution of the equation 7x plus 9 equals 51?
7x + 9 = 51 7x = 42 x = 42/7 = 6
What is the equation of the line that it is perpendicular to y7x-3 and passes through the origin?
If you mean 7 = 7x-3 then the perpendicular slope is -1/7 and the equation is y = -1/7x
How do you do the work to find the answer to 7x plus 2 equals -19?
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?
What is the solution to x-8x equals 1?
x - 8x = 1 Perform the indicated subtraction on the left side: -7x = 1 Divide each side of the equation by -7 : x = - 1/7
How do you do this equation 7x-7 equals 14?
Solution:7x - 7 = 147x = 14 + 77x = 21x = 21/7x = 3Checking:7(3) - 7 = 1421 - 7 = 1414 = 14
What is the solution of the equation 7x plus 9 equals 51?
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
How do you do the work to find the answer to 7x plus 2 equals -19?
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?
What is the solution to x-8x equals 1?
x - 8x = 1 Perform the indicated subtraction on the left side: -7x = 1 Divide each side of the equation by -7 : x = - 1/7
What do you do if the solution is 8x equals 7x?
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
Does (1, –7) make the equation y = –7x true?
yes
What is the solution of the equation 3x plus 17 plus 5x equals 7x plus 10?
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
To solve 7x equals 56 you must do what to both sides?
7x = 56 To find the solution for x, you should divide both sides of the equation by 7 to get x = 8.
What is 7x-2x equals 7 plus -2x?
It is an equation and the value of x is 1
What is -7x-6 equals 29?
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
How do you solve 7x equals 7?
It is solved when you have it in the form of (x = some number). In this case, you have 7x on one side, which is 7 times x. You need to divide both sides by 7, so you have: 7x / 7 = 7/7. On the left side, this becomes x. On the right side 7/7 = 1, so x=1 solves the equation. If you 'plug in' x=1 to the original equation, you get 7(1) = 7, or 7 times 1 equals 7, which is true.
