Question

1)4x+5(3-2)=5-11x 3)8x+3(7-2x)=4x+3

Answer 1

Ответ:

1) х = 0; 3) х = 9.

Пошаговое объяснение:

1) 4х+5(3-2) = 5-11х

4х+15-10 = 5-11х

4х+11х = -15+10+5

15х = 0

х = 0;

3) 8x+3(7-2x) = 4x+3

8х+21-6х = 4х+3

8х-6х-4х = -21+3

-2х = -18

делим обе части уравнения на (-2)

х = 9.

Answer 2

To solve the given equations, we need to find the values of 'x' that make the equations true. Let's solve them step-by-step:

1. 4x + 5(3 - 2) = 5 - 11x

Step 1: Simplify the equation by performing the operations inside the parentheses: 4x + 5(1) = 5 - 11x

Step 2: Distribute the 5 on the left side of the equation: 4x + 5 = 5 - 11x

Step 3: Move the variable terms (with 'x') to one side of the equation and the constant terms to the other side: 4x + 11x = 5 - 5

Step 4: Combine the 'x' terms and simplify the constants: 15x = 0

Step 5: Solve for 'x': x = 0

So, the solution to the first equation is x = 0.

2. 8x + 3(7 - 2x) = 4x + 3

Step 1: Simplify the equation by performing the operations inside the parentheses: 8x + 3(7) - 3(2x) = 4x + 3

Step 2: Distribute the 3 on both sides of the equation: 8x + 21 - 6x = 4x + 3

Step 3: Move the variable terms (with 'x') to one side of the equation and the constant terms to the other side: 8x - 6x - 4x = 3 - 21

Step 4: Combine the 'x' terms and simplify the constants: -2x = -18

Step 5: Solve for 'x': x = -18 / -2 x = 9

So, the solution to the second equation is x = 9.
