2x-4 plus 3 equals 5x-6?
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
How do you graph 5x-6y equals -30?
5x -6y=-30 5x-6y=30 (2x+3y) (2x-3y)=30 4x+6y=30 4x=30 x=30/4
Ten x square minus nine x plus two?
10x² - 9x + 2 = 10x² - 5x - 4x + 2 = 5x(2x - 1) - 2(2x - 1) = (5x - 2)(2x - 1). * (Note that -5 and -4 have a sum of -9; and that their product is +20, which is also the product of +10 and +2. That answers any question of how we knew to split the -9x into -5x and -4x, in the first step, above. This method will work whenever one factorises any factorisable quadratic expression; although I will not attempt here to explain the theory of why.) * The roots are 2/5 and ½. That is, 10x² - 9x + 2 = 0 exactly when, either, 5x - 2 = 0, or 2x - 1 = 0.
How do you solve 2x equals 11x plus 4?
2x = 11x + 4 Subtract 11x from both sides: -9x = 4 Divide both sides by -9: x = 4/(-9) = -0.444...
How do you solve 2x plus 4 plus 4x -5x plus 3 plus x?
If there are no equals you can simplify this by collecting all the x values together and use the addition property of signed numbers. 2x+4x-5x+x=2x; 4+3=7. 2x+7 is the simplified statement.
How do you solve 9x-5x equals 7?
9x-5x=4x, 7/4=1.75, x=1.75
5x plus 2 equals 2x-10?
5x+2=2x-10 x=-4
Solve 3x plus 2x equals -4?
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
How do you solve y equals y equals 2x-1 y equals 5x-13?
y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7
5x plus 2 equals 9x-4?
x=2/3
What is 5x equals 9x-16?
If you are looking for the value of x... X=4
What is 9x plus 5 equals 5x plus 17?
9x + 5 = 5x + 179x + 5 - 5x = 179x - 5x = 4x5-4x=1717-5=1212 divided by 4 = 3x=3
What is answer to 5x-4 equals 3x plus 6 equals?
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
How do you solve 7x equals 2x-4?
7x=2x-4 5x=-4 x=-4/5
What is the answer to 9x minus 4 equals 7x plus 8?
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
7x plus 19 equals -2x plus 55?
answer is 4 7x+19=-2x+55 +2x +2x 9x+19= 0 55 -19 -19 9x = 36 9 9 =4
What is (4x plus 3 ) plus (-2x plus 8)?
5x + 3 - 4 + 4x = 9x -1
