18-6r equals 0 What does r equal?
Divide both sides by 6: 3 - r = 0, so r = 3 satisfies the equation.
What is 4x equals 5x?
Oh, what a happy little equation we have here! When we have 4x equals 5x, we simply need to remember that both sides should be equal. So, if we subtract 4x from both sides, we get x equals 0. It's all about finding that balance and making sure both sides of the equation are in harmony.
What does x equal in the equation -X over 6 minus 8 equals 0?
-x/6 - 8 = 0 Add 8 to both sides: -x/6 = 8 Multiply both sides by 6: -x = 48 Change the sign on both sides x = -48
What value makes this equation true 5a equals a?
the value that makes this ewuation true 5a=a is 2a
5y plus 1 equals 4y - 1?
5y + 1 = 4y - 1 Subtract 4y from both sides of the equation. y + 1 = -1. Add 1 to both sides of the equation. y + 2 = 0 Subtract 2 from both sides of the equation. y = -2

3x2 - x - 24?
To solve a two-step equation you want to isolate the variable in the equation. In this case it is X. first: 3X-24=0 +24 +24 add 24 to both sides second: 3X=24 3X=24 divide by three on both sides 3 3 solution: X=8 you can check your work by plugging in the X value so... 3x8-24=0 24-24=0 0=0 when both sides of the equation equal each other the X value is correct.
Is the equation 2x equals 3x is always false?
No. It is true if and only if x=0. Note that for x not equal to 0, we can divide both sides of the equation by x giving 2=3 which is false. Division by 0 is undefined so we must check x=0 manually and indeed, it solves the equation.
7h - 2 -51 what is h?
Set the equation equal to 0: 7h - 2 - 51 = 0 add -2 and -51 to both sides: 7h = 53 Divide h = 53/7
What value makes this equation true 5a equals a?
the value that makes this ewuation true 5a=a is 2a
The equation 8-4x=0 has how many real solutions?
the equation has exactly 1 real solution. 8-4x=0 -> add 4x to both sides. 8=4 -> divide both sides by 4. 2=x.
Why can't you multiply both sides of the equation by zero?
Any variable multiplied by zero equals zero, so you can multiply both sides of the equation by zero, but you just destroy any form of a solution you may have. For example: x = 5 x*0 = 5*0 0 = 0 Yup! By the way, what is x? Algebra is basically finding a missing variable or finding a relationship between many variables. Multiplying by 0 removes information that is crucial to solving for variables.
5y plus 1 equals 4y - 1?
5y + 1 = 4y - 1 Subtract 4y from both sides of the equation. y + 1 = -1. Add 1 to both sides of the equation. y + 2 = 0 Subtract 2 from both sides of the equation. y = -2
What is the solution for 3x-y equals 0 and 5y equals 15?
First Equation ~ 3x-y=0 Second Equation ~ 5y=15Divide by five on both sides on the second equation to get y=3Substitute y=3 into the first equation to get 3x-(3)=0Add the three to both sides to cancel the three on the left to get 3x=3Divide both sides by 3 to get x=1
What is an example of 0 as a solution for an equation?
Here is an example: x + 5 = 5If you subtract five from both sides, you get x = 0, which is an example of getting 0 as a solution for an equation.
