Question

49+x=7, 50+q=175, 48+2a+a=60 помните решить примеры пожалуйста​

Answer 1

Пошаговое объяснение:

переносим числа в правую сторону, а буквы в левую (меняем знак) 49+x=7 => x=7-49 => x=-42

по образу и подобию:

50+q=175 => q=175-50 => q=125

48+2a+a=60 => 3a=12 => a=4

Answer 2

Ответ:

1)49 + х = 7

х = 7 - 49

х = - 42

2) 50 + q = 175

q = 175 - 50

q = 125

3)48 + 2а + а = 60

48 + 3а( 2а + а = 3а) = 60

3а = 60 - 48

3а = 12

а = 12 : 3

а = 4

Answer 3

Certainly! Let's solve each of the equations step-by-step:

1. 49 + x = 7

To solve for x, we need to isolate x on one side of the equation. We can do this by subtracting 49 from both sides:

49 + x - 49 = 7 - 49

x = -42

So, the value of x is -42.

2. 50 + q = 175

To solve for q, we need to isolate q on one side of the equation. We can do this by subtracting 50 from both sides:

50 + q - 50 = 175 - 50

q = 125

So, the value of q is 125.

3. 48 + 2a + a = 60

Combine like terms:

48 + 3a = 60

Now, to solve for a, we'll isolate a on one side of the equation. First, subtract 48 from both sides:

48 + 3a - 48 = 60 - 48

3a = 12

Finally, divide both sides by 3 to find the value of a:

a = 12 / 3

a = 4

So, the value of a is 4.

Final solutions: x = -42 q = 125 a = 4
