What is 2x3 plus 11x equals 6x?
your equation is this... 2x3 + 11x = 6x 2x3 + 5x = 0 x(2x2 + 5) = 0 x = 0 and (5/2)i and -(5/2)i
-8x plus 5 - 3x equals -6?
-8x + 5 - 3x = -6Combine the 'x' terms on the left side:-11x + 5 = -6Subtract 5 from each side:-11x = -11Divide each side by -11:x = 1
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

Use addition or substitution to find the value of x for this set of equations 12x-5 equals 30 and y equals 2x-6?
12x - 5 = 30Add 5 to each side:12x = 35Divide each side by 12:x = 35/12=======================y = 2x - 6Substitute the value of 'x' :y = 2(35/12) - 6Clear parentheses:y = 35/6 - 6y = 35/6 - 36/6y = -1/6
How do you solve 12 x - 5 equals 11 x plus 5?
12x - 5 = 11x + 5(1) add 5 to both sides:12x - 5 + 5 = 11x + 5 + 512x = 11x + 10(2) next subtract 11x from both sides:12x - 11x = 11x - 11x + 10x = 10
Y equals -x plus 12x-y equals 5 solve by substitution?

How do you solve 5 over 11X - 7 equals 2?
Write as an equation with division before subtraction. 5/11x-7=2 5/11x=9 mult both sides by 11x 5=99x 99x=5 x=5/99
What are the x coordinates when the parabolas of y equals 4x squared -12x -3 and y equals x squared plus 11x plus 5 intersect each other?
If: y = 4x^2 -12x -3 and y = x^2 +11x +5 Then: 4x^2 -12x -3 = x^2 +11x +5 Transposing terms: 3x^2 -23x -8 = 0 Factorizing: (3x+1)(x-8) = 0 => x = -1/3 or x = 8 Therefore the x coordinates are: -1/3 and 8
How do you solve this problem 12x when x 5?
When x = 5, 12x = 12*5 = 60.
How do you solve 12x plus 17 equals 7?
12x + 17 = 7 Subtract 17 from both sides: 12x = -10 Divide both sides by 12: x = -10/12 = -5/6
How do you solve 5 over 4x plus 7 over 12x (adding rational expressions)?
5/4x+7/12x is the same as 15/12x+7/12x = 21/12x
How do you solve 6y equals 12x plus 32?
6y = 12x+32 Divide all terms by 6: y = 2x+5 and 1/3 which is now in slope intercept form
What is x if 13x plus 15 equals 11x-5?
13x + 15 = 11x - 5 2x = -20 x = -10
What is the answer to -11x equals 55?
x=55/-11=-5
How can you rewrite equation x squared plus 12x plus 5 equals 3?
x2+12x+5 = 3 x2+12x+5-3 = 0 x2+12x+2 = 0
How do you factor the expression 30 plus 12x equals?
30+12x = 6(5+2x)
