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?
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 are intercepts for 7x-3y equals 21?
If the equation is 7x - 3y = 21 then (3, 0) and (0, -7).
Does the equation 7x-56x 3 have exactly one solution?
It has no solution because without an equality sign it is not an equation.
What is ten x plus fifteen equals seven x minus twenty-one simplified?
10x+15 = 7x-21 10x-7x = -21-15 3x = -36 x = -12 Which is the solution to the above equation when simplified.

What is 9x - 4 equals 7x - 6?
This is a linear equation. The value x = -1 is the solution to this equation.
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
