Question

СРОЧНО!!!!! ДАЮ 50 БАЛІВ. Розв’яжіть рівняння: 1) (х-348) + 159 = 601; 2) 957 – (х + 336) = 428; 3) 36 : (х – 2) = 4.

Answer 1

Ответ:1)(х-348)+159=601

РЕШЕНИЕ:

х-348=601-159

х-348=442

х=348+442

х=790

2)957-(х+336)=428

РЕШЕНИЕ:

х+336=957-428

х+336=529

х=529-336

х=193

3)36÷(Х-2)=4

РЕШЕНИЕ:

х-2=36÷4

х-2=9

х=9+2

х=11

Answer 3

1. (х - 348) + 159 = 601

To solve this equation, we'll simplify it step by step:

First, let's remove the parentheses:

х - 348 + 159 = 601

Next, combine like terms:

х - 189 = 601

Now, isolate the variable by adding 189 to both sides:

х - 189 + 189 = 601 + 189

х = 790

Therefore, the solution to the equation is х = 790.

2. 957 - (х + 336) = 428

Let's simplify this equation:

957 - х - 336 = 428

Combine like terms:

-х + 621 = 428

Now, isolate the variable by subtracting 621 from both sides:

-х + 621 - 621 = 428 - 621

-х = -193

To solve for х, multiply both sides by -1 to change the sign:

-х * (-1) = -193 * (-1)

х = 193

The solution to the equation is х = 193.

3. 36 / (х - 2) = 4

To solve this equation, we'll cross-multiply and solve for х:

36 = 4 * (х - 2)

Distribute the 4 on the right side:

36 = 4х - 8

Now, isolate the variable by adding 8 to both sides:

36 + 8 = 4х - 8 + 8

44 = 4х

Divide both sides by 4:

44 / 4 = 4х / 4

11 = х

The solution to the equation is х = 11.

Therefore, the solutions to the equations are:

1. х = 790
2. х = 193
3. х = 11
