5) х=16

Answer 2

1) 250 - Зу = 115 2) х + 3x + 2 = 3x = 120 3) (48 - x) / 8 = 4

Solution:

1) To solve the equation 250 - Зу = 115, we need to isolate Зу on one side of the equation. We can do this by subtracting 115 from both sides:

250 - Зу - 115 = 115 - 115 135 - Зу = 0

Now, we can isolate Зу by subtracting 135 from both sides:

135 - Зу - 135 = 0 - 135 -Зу = -135

To solve for Зу, we need to multiply both sides by -1:

-1 * -Зу = -1 * -135 Зу = 135

Therefore, the value of Зу is 135.

2) To solve the equation х + 3x + 2 = 3x = 120, we need to simplify the equation first.

Combining like terms, we have:

4x + 2 = 3x = 120

Next, we can isolate the variable x by subtracting 3x from both sides:

4x - 3x + 2 = 3x - 3x = 120 - 3x x + 2 = 120 - 3x

To isolate x further, we can subtract 2 from both sides:

x + 2 - 2 = 120 - 3x - 2 x = 118 - 3x

To solve for x, we need to isolate it on one side of the equation. We can do this by adding 3x to both sides:

x + 3x = 118 - 3x + 3x 4x = 118

Finally, we can solve for x by dividing both sides by 4:

4x / 4 = 118 / 4 x = 29.5

Therefore, the value of x is 29.5.

3) To solve the equation (48 - x) / 8 = 4, we can start by multiplying both sides by 8 to eliminate the fraction:

8 * (48 - x) / 8 = 4 * 8 48 - x = 32

Next, we can isolate x by subtracting 48 from both sides:

48 - x - 48 = 32 - 48 -x = -16

To solve for x, we need to multiply both sides by -1:

-1 * -x = -1 * -16 x = 16

Therefore, the value of x is 16.

In summary, the solutions to the given equations are: 1) Зу = 135 2) x = 29.5 3) x = 16
