3x plus 2 equals 5x?
3x+2 = 5x so 2x = 2 and hence x = 2/2 = 1
3x plus 5x equals 2x plus 2?
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
How do you solve 5x-2 3x-6?
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
How do you solve 3X plus 2Y equals 16 and 5X plus 3Y-18 equals 4Y by substitution?
First collect like terms in the second equation: 5x - 18 = 4y - 3y ie y = 5x - 18 Substitute this for the term in y in the first equation, getting 3x + 2(5x - 18) = 16 ie 3x + 10x - 36 = 16 ie 13x = 16 + 36 so x = 4 and y = 5 x 4 - 18 ie 2.
What is x if 3x plus 2 plus 3x-4 equals 44?
x = 7 and 2/3
How do you solve 5X plus 2 equals 3X-6?
5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4
3x plus 2 equals 5x?
3x+2 = 5x so 2x = 2 and hence x = 2/2 = 1
What is 5x-10 equals 3x plus 2?
5x - 10 = 3x + 2 5x - 3x = 2 + 10 2x = 12 x = 12/2 x = 6
3x plus 2 plus 2x equals 7?
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
3x plus 5x equals 2x plus 2?
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
Solve 5x-3 equals 3x plus 2?
3
Is 5x plus 6y equals 3x plus 2 a linear equation?
yes it is!
6-3x equals 5x-10x plus 10?
6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2
What iS 5x-7 plus 2x equals 3x-2 plus 4x?
It is a mathematical equation, usually written like this: 5x - 7 + 2x = 3x - 2 + 4x
How do you solve for 5x plus y equals 1 and 3x plus 2y equals 2?
For 5x+y=1, you would subtract 5x from each side, so you would get y=1-5x For 3x+2y=2, you would subtract 3x from each side, and then divide by 2. 2y=2-3x y=1-(3/2)x
What is 6-3x equals 5x-10x plus 2?
6-3x = 5x-10x+2 4 = 8x-10x 4 = -2x x = -2
5x plus 2 equals 2 times x plus 6?
3x=-4 is as far as I can work it.
