2x plus 3y equal 40 -2x plus 2y equal 20?
2x+3y=40-2x+2y=20Since 2x does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 2x from both sides.3y=-2xDivide each term in the equation by 3.(3y)/(3)=-(2x)/(3)Simplify the left-hand side of the equation by canceling the common terms.y=-(2x)/(3)if you were solving for x It would be x=-(3y)/2
How do you solve -9x-3 plus 4x equals -2x?
Equation: 9X-3+4X=-2X You are going to want to factor this equation into something that looks like X=35, 35 being a randomly selected number. Step 1) Add 3 to both sides 9X+4X=-2X+3 Step 2) Add 2X to both sides 9X+4X+2X=3 Step 3) Simplify 15X=3 Step4) Divide both sides by 15 X=3/15
4x2 - 0x - 9?
(2x - 3)(2x + 3)(2x-3)(2x+3)
Antiderivative of x cubed divided by 3?
x4/12 since derivative of x4/12 is 4x3/12 or x3/3
How do you work out 2x - 3 - 6x?
2x -3 - 6x = 0 -3 = 6x - 2x -3 = 4x x = -3/4
Simplify x - 2x plus 3?
x - 2x + 3 = 3 - x
How do you simplify 2x plus 4x plus 3?
2x + 4x + 3 = 6x + 3
Simplify 2x-5x+x?
-3
Square root of 24 times x to the 4th power divided by square root 3x?
The question is ambiguous. Do you mean √(24*x4) or √24*x4? √(3x) or √3*x? The answer to √(24*x4) / √(3x) = (8x3) = 2x*√(2x)
Simplify 7-3 4-2x -10x?
This will simplify to 27 - 12x, assuming the original equation was 7-34-2x-10x.* * * * *No, it will not! If the assumption is correct, it will simplify to -27-12x.
Simplify 2x 3 x - 4?
X = 0.8

Answer this question…A. x4 + 2x3 + 9x2 + 4 B. x4 + 4x3 + 9x2 + 4 C. x4 + 2x3 + 9x2 + 4x + 4 D. x4 + 2x3 + 9x2 - 4x + 4
Simplify the algebraic expression 3x 3 - 2x 3?
3x+3-2x=3 x+3=3 x-0
15x-3 equals 2x plus 1?
OK, SO 15x-3 = 2x+1 15x - 3 + 3 = 2x + 1 + 3 (add three to each side) 15x=2x+4 (simplIfy) 15x-2x=2x-2x+4 (subtract 2x from each side) 13x=4 (simplify) (13x/13)=(4/13) (divide each side by 13) x≈0.30769231
How can you factor to simplify 6x to the third -9x squared over 2x-3?
(6x^3-9x^2) / (2x-3) = 3x^2((2x-3) / (2x-3) = 3 x ^2 (3 x squared)
Simplify -7 plus 2(x-3)?
-7 + 2(x-3) = -7+2x-6 = 2x - 13
