Assuming the equation given is 3x - 6 = 30, solve for x by isolating the known from the unknown and dividing by the number of x's: 3x - 6 = 30 (isolate the known from unknown by adding 6 to each side) 3x = 36 (now divide both sides by the nuber of x's [3] to solve for x) x = 12

What is 3x plus 6 equals 30?
3x + 6 = 30 Therefore, 3x = 24 x = 24/3 x = 8
3x - 6y equals 30 y equals -6x plus 34?
3x-6y=30 y=34-6x substitute the the value for y from the second equation into the first equation. 3x-6(34-6x)=30 3x-204+36x=30 39x-204=30 39x=234 x=234/39 x=6 Substitute this value of x into equation 2. y=34-6(6) y=34-36 y=-2
3x plus 20 and 2x-10 what is the value of x?
If: 3x+20 = 2x-10 Then: x = -30
What if linear equations starts with a negative?
Either move the negative over to the other side to become positive, or divide the entire equation by -1 to get it to a positive. Example: -3x + 12 = 30 Move the -3x over to get 12 = 30 + 3x 12 - 30 = 3x - 18 = 3x - 6 = x OR Divide by -1 to get 3x - 12 = - 30 3x = - 30 + 12 3x = -18 x = -6
When do you use the distributive property when solving equations?
when a problem looks like this: for example: 6(5+3x) 6 x 5 = 30 and 6 x 3x = 18x so it would be 30 + 18x
What is 3x plus 6 equals 30?
3x + 6 = 30 Therefore, 3x = 24 x = 24/3 x = 8
What is the value of x wen 3x-520 30?
If you mean: 3x-520 = 30 then the value of x is 183 and 1/3
3x - 6y equals 30 y equals -6x plus 34?
3x-6y=30 y=34-6x substitute the the value for y from the second equation into the first equation. 3x-6(34-6x)=30 3x-204+36x=30 39x-204=30 39x=234 x=234/39 x=6 Substitute this value of x into equation 2. y=34-6(6) y=34-36 y=-2
-3x plus 6 equals -30?
-3x + 6 = -30 -3x = -30 - 63x = 36x = 36/3Therefore, x = 12.
What is equivalent to 3x - 6 6?
If you mean: 3x-6 = 6 then the value of x is 4
What is absolute value -3x-2 equals -6?
-3x - 2 = -6 -3x = -6 + 2 -3x = -4 -x = -4/3 x = 4/3 The absolute value is therefore 4/3.
What is the answer to y equals 3x 3x plus 4y equals 30?
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
3x plus 20 and 2x-10 what is the value of x?
If: 3x+20 = 2x-10 Then: x = -30
What would be the value of x in x+x+x=30?
Solution: x + x + x = 30 3x = 30 x = 30/3 x = 10
What is the value of x in the equation -3x - 8 10?
x = -6
What if linear equations starts with a negative?
Either move the negative over to the other side to become positive, or divide the entire equation by -1 to get it to a positive. Example: -3x + 12 = 30 Move the -3x over to get 12 = 30 + 3x 12 - 30 = 3x - 18 = 3x - 6 = x OR Divide by -1 to get 3x - 12 = - 30 3x = - 30 + 12 3x = -18 x = -6
What value for X makes the equation 3x plus 3 equals 2x plus 6 true?
If 3x + 3 = 2x + 6 then 3x - 2x = 6 - 3 x = 3
