3x - 2x + 4 = 0 3x - 2x = -4 x = -4
3x+7=2x-5 x=-12
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
An equation where x equals 3.
If: 2x+5y = 2 and -3x-y = -3Then it works out that: x = 1 and y = 0
3x - 2x + 4 = 0 3x - 2x = -4 x = -4
3x+7=2x-5 x=-12
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
2x+3y=13 3x-y=3 x=2
An equation where x equals 3.
2x - 3x = -x
If: 2x+5y = 2 and -3x-y = -3Then it works out that: x = 1 and y = 0
Let's dive into this problem: Given numbers/terms are: -2x and x.. We are asked to subtract both.. -2x-x = -(2+1)x = -3x.. Therefore, the answer is -3x..
6 - 3x = 4 - 2x 6 = x + 4 x = 2 Check it. 6 - 6 = 4 - 4 It checks.
3x2 - 2x - 5 = (3x - 5)(x + 1) = 0 gives a solution of x = 5/3 or -1. Was that what you wanted?
3x2 + 2x - 8 = 0 is a quadratic equation.
2x minus 3x is equal to -x.
