5x plus 4y equals 12 7x - 6y equals 40?
(4, -2)
How many solutions are there to the equation below 5x plus 48 plus 7x 12(x plus 4)?
4
What is the sum of -3x -7x plus 9 and -5x plus 6x-4?
It is -9x plus 5.
What is 11x plus 2 equals 26 plus 7x?
11x + 2 = 26 + 7x Subtract 7x from both sides: 4x + 2 = 26 Subtract 2 from both sides: 4x = 24 Divide both sides by 4: x = 6
How do you factor 10x2 7x - 12?
If it's + 7x, the answer is (2x + 3)(5x - 4) If it's - 7x, the answer is (2x - 3)(5x + 4)
What is 5x 4 7x if x6?
5x+4+7x
What is 3 plus 7x plus 5-2x-4?
5x+4
What is 2x plus 5x plus 4 equals 25?
2X + 5X + 4 = 25 add the X terms together 7X + 4 = 25 subtract 4 from each side 7X + 4 - 4 = 25 - 4 7X = 21 divide both sides integers by 7 (7/7)X = 21/7 X = 3 ----------check in original equation 2(3) + 5(3) + 4 = 25 6 + 15 + 4 = 25 25 = 25 checks
How do you factor 10x2 plus 7x - 12?
(5x - 4)(2x + 3)
What is the answer to 5x plus 8 equals 7x?
7x-5x=8 2x=8 x=4
What is 21x cubed-23x squared-76x-32 divided by 7x plus 4?
(21x3-23x2-76x-32)/(7x+4) = [3x2(7x4) -5x(7x+4)-8(7x+4)]/(7x+4)=3x2-5x-8
5x+3y=26-2x+7y=6?
We can solve this system of equations by subtracting the second equation from the first: 5x + 3y = 26 -2x + 7y = 6 7x + 4y = 20 Now we can divide both sides by 4 to isolate the y-term: 7x + 4y = 20 4 4 4 7x/4 + y = 5 Now we can subtract 7x/4 from both sides to isolate the x-term: 7x/4 + y = 5 -7x/4 -7x/4 y = 5 - 7x/4 Plugging this back into the first equation and simplifying, we have: 5x + 3(5 - 7x/4) = 26 5x + 15 - 21x/4 = 26 -16x/4 = 11 x = -11/16 Plugging this back into the equation for y, we have: y = 5 - 7x/4 = 5 - 7(-11/16)/4 = 5 + 33/16 Therefore, the solution to the system is x = -11/16 and y = 33/16.
How do you solve 7x equals 2x-4?
7x=2x-4 5x=-4 x=-4/5
What is 8x-4 equals -7 plus 5x?
8x - 4 = -7 + 5x8x - 5x - 4 = -7 + 5x - 5x subtract 5x from both sides3x - 4 + 4 = -7 + 4 add 4 to both sides3x = -3x = -3/3 = -1
How do you factor 35x2-36x-32?
35x2-36x-32 = (5x-8)(7x+4) when factored. 35*-32 = -1120 = -56*20 since -56+20 = -36 (35x - 56)(35x + 20) divide by 7 and 5 the coefficients of the two binomials (5x - 8)(7x + 4) or 35x2 - 56x + 20x - 32 = 7x(5x - 8) + 4(5x - 8) = (5x - 8)(7x + 4)
What is the answer for 12x minus 4 equal 7x minus 21?
