Question

11x-9=4x=19; 7x-5(2x+1)=5x+15 Помогите пожалуйста (ОЧЕНЬ НАДО)

Answer 1

11x-4x=19+9
7x=28
x=4

7x-10x-5=5x+15
7x-10x-5x=15+5
-8x=20
x= - 2.5

Answer 2

Solving the Equation 11x - 9 = 4x + 19

To solve the equation 11x - 9 = 4x + 19, we need to isolate the variable x on one side of the equation. Here's how we can do it step by step:

Step 1: Combine like terms on both sides of the equation: 11x - 9 = 4x + 19

Step 2: Move the variable terms to one side and the constant terms to the other side: 11x - 4x = 19 + 9

Simplifying the equation gives us: 7x = 28

Step 3: Solve for x by dividing both sides of the equation by 7: 7x/7 = 28/7

Simplifying further, we get: x = 4

Therefore, the solution to the equation 11x - 9 = 4x + 19 is x = 4.
