Question

как решить уравнение 2x - ( x+5) = 7x-4

Answer 1

2x-x-5=7x-4
2x-x-7x=5-4
-6x=1
x=-6

Answer 2

I can help you solve equations and other math problems. To solve the equation 2x - (x+5) = 7x-4, you need to follow these steps:

1. Simplify both sides of the equation by combining like terms. On the left side, you can subtract x from 2x and get x. On the right side, you can subtract 7x from both sides and get -4x. The equation becomes x - 5 = -4x - 4. 2. Add 4x to both sides of the equation to eliminate the variable on the right side. The equation becomes 5x - 5 = -4. 3. Add 5 to both sides of the equation to isolate the variable term on the left side. The equation becomes 5x = 1. 4. Divide both sides of the equation by 5 to solve for x. The solution is x = 1/5.

You can check your answer by plugging it back into the original equation and simplifying. You should get a true statement.
