12x+30=15x-20. Add 20 to both sides.
12x+50=15x. Subtract 12x from both sides.
50=3x. Divide both sides by 3.

How do you factor the expression 30 plus 12x equals?
30+12x = 6(5+2x)
What is the answer to 12x-30 equals 114?
12x-30=114 12x=114+30 x=144 / 12 therefore x=12
What does x equal in 2x squared plus 6 equals 30?
2x2 + 6 = 30 is your statement.2x2 = 24x2 = 12x = ±√12x = ±√(4*3)x = 2√3 or x = -2√3
12x - 5y equals 30 and y equals 2x - 6 what is the y value?
12x - 5(2x - 6) = 30 12 x - 10x + 30 = 30 2x = 0, x = 0 y = -6
Y equals 5-2x and 4x plus 6y equals -2 solve by substitution?
y = 5 - 2x so 4x + 6(5 - 2x) = -2 ie 4x + 30 - 12x = -2 Subtract 30 from each side: 4x - 12x = -32 ie -8x = -32 so x = 4 and y = -3
How do you factor the expression 30 plus 12x equals?
30+12x = 6(5+2x)
What is the answer to 12x-30 equals 114?
12x-30=114 12x=114+30 x=144 / 12 therefore x=12
What does x equal in 2x squared plus 6 equals 30?
2x2 + 6 = 30 is your statement.2x2 = 24x2 = 12x = ±√12x = ±√(4*3)x = 2√3 or x = -2√3
12x - 5y equals 30 and y equals 2x - 6 what is the y value?
12x - 5(2x - 6) = 30 12 x - 10x + 30 = 30 2x = 0, x = 0 y = -6
What is the x value of 12x - 5y equals 30 y equals 2x - 6?
Substitute 2x - 6 for y in first equation: 12x - 5(2x - 6) = 30 ie 12x - 10x + 30 = 30 so 2x = 0 making x = 0 and y = -6
What are the release dates for 15x20 - 2010?
15x20 - 2010 was released on: USA: 30 April 2010
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)
How do I sovle -0.2x2 plus 12x plus 11 equals 0?
-0.2x2+12x+11 = 0 Using the quadratic equation formula will give you two solutions which are: x = 30 + the square root of 955 = 60.90307428 to 8 decimal places. or: x = 30 - the square root of 955 = -0.90307428 to 8 decimal places.
Thirty over twelve equals what over eighteen?
45 30/12 = x/18; 12x = 30 x 18; 12x = 540; x = 540 ÷ 12 = 45
Y equals 5-2x and 4x plus 6y equals -2 solve by substitution?
y = 5 - 2x so 4x + 6(5 - 2x) = -2 ie 4x + 30 - 12x = -2 Subtract 30 from each side: 4x - 12x = -32 ie -8x = -32 so x = 4 and y = -3
How do you solve the equation 2x plus 30 equals equals 12x-50?
Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x
What is 30 plus 30 plus 30 plus 30 plus 30 plus 30 equals?
30 + 30 + 30 + 30 + 30 + 30 = 180
