The goal is to make the equation equal X.45=-15-5x
The value of 'c' that makes the equation a true statement is the answer.Here's how to find it:Write the equation:3c - 15 = 17 - cAdd 'c' to each side:4c - 15 = 17Add 15 to each side:4c = 32Divide each side by 4:c = 8
13x = 15 - 2 x Solve for x 1. Get the x's on one side. Add 2x to each side. 13x + 2x = 15 - 2x + 2x This is the same as 15x = 15 2. Get x by itself. Divide each side by 15. 15x/15 = 15/15 x = 1
-- Add 5p to each side of the equation. -- Add 15 to each side of the equation. -- Look at the equation and find the one last step that will give you " p = a number ", which is the solution.
Divide both sides of the equation by 15

" 6x equals 3x plus 15 " is a simple linear equation in 'x'.Before you can "do" it, you have to know what it is that you want to do.In other words, you have to know what the question is.The question is: What number does ' x ' have to be to make that statement true ?Here's how to find it:Do anything to either side of the equation that you have to do in order to get ' x 'all by itself. But if you do anything to one side, you have to do it to both sides.6x = 3x + 15Subtract 3x from each side of the equation:3x = 15Divide each side by 3:x = 5

15% of ? = $140Set it up as an equation by changing the percent into a decimal..15x=140So, divide both sides by .15. This will cancel out .15 on the left side of the equation, leaving x alone. The right side will be 140/.15 which equals 933.33Your new equation is x=933.33Now change that into money, and your answer is $933.33

13x = 15 - 2 x Solve for x 1. Get the x's on one side. Add 2x to each side. 13x + 2x = 15 - 2x + 2x This is the same as 15x = 15 2. Get x by itself. Divide each side by 15. 15x/15 = 15/15 x = 1
Assuming the equation is 3x=15, you just need to divide each side of the equation by three. On the left, x times three divided by three is one times x, or just x. On the right side, fifteen divided by three is five. So you are left with x=5.
-10e + 15 = 95 - 30eAdd 30e to each side of the equation:20e + 15 = 95Subtract 15 from each side:20e = 80Divide each side by 20:e = 4
First, set up the equation you are given: 15 - 2p = 9 Subtract 15 from each side of the equation: 15 -2p - 15 = 9-15 Then, you should have: -2p = -6 Divide each side by -2: (-2p)/(-2) = (-6/-2) Solve for p: p = 3
