Question

1). х:4-69=120 2). 200-х*2=162 3). 14*х+19=47

Answer 1

Ответ:

1) 756

2) 19

3) 2

Пошаговое объяснение:

1) х:4 - 69 = 120

Х:4 = 120+69

Х:4 = 189

Х = 189×4

Х = 756

2) 200-2х=162

2х= 200 - 162

2х = 38

Х = 19

3) 14х+19=47

14х= 47 - 19

14х = 28

Х = 2

Answer 2

To solve these equations, we'll find the value of variable "x" in each case:

1. х:4 - 69 = 120

Step 1: Simplify the left side of the equation by performing the division: х/4 - 69 = 120

Step 2: Move the constant term (69) to the other side by adding it to both sides of the equation: х/4 = 120 + 69

Step 3: Combine the constants: х/4 = 189

Step 4: Isolate "x" by multiplying both sides of the equation by 4: x = 4 * 189 x = 756

So, the solution to the first equation is x = 756.

2. 200 - х * 2 = 162

Step 1: Move the constant term (200) to the other side by subtracting it from both sides of the equation: 200 - х * 2 - 200 = 162 - 200

Step 2: Simplify both sides: -х * 2 = -38

Step 3: Isolate "x" by dividing both sides of the equation by -2: x = (-38) / (-2) x = 19

So, the solution to the second equation is x = 19.

3. 14 * х + 19 = 47

Step 1: Move the constant term (19) to the other side by subtracting it from both sides of the equation: 14 * х = 47 - 19

Step 2: Simplify both sides: 14 * х = 28

Step 3: Isolate "x" by dividing both sides of the equation by 14: x = 28 / 14 x = 2

So, the solution to the third equation is x = 2.
