Question

15-(2х^2-4х)-(7х-2х^2)=0 Решите уравнение

Answer 1

15-(2х²-4х)-(7х-2х²)=0
15-2х²+4х-7х+2х²=0
-3х+15=0
-3х=-15 |:(-3)
х=5.

Answer 2

15 - (2x^2 - 4x) - (7x - 2x^2) = 0

First, let's simplify the equation by combining like terms: 15 - 2x^2 + 4x - 7x + 2x^2 = 0 15 - 3x = 0

Now, let's isolate the variable x by moving the constant term to the other side of the equation: -3x = -15 x = 5

So, the solution to the equation is x = 5.
