Question

75*x - 30 = 33075*4 + x = 330​

Answer 1

Ответ:

1)75*×-30=330

75×=330-30

75×=30

х=4

2)75*4 + x = 330

300+х=300

х=330-300

х=30

Answer 2

It appears you have two equations:

1. 75x - 30 = 330
2. 75*4 + x = 330

Let's solve them one by one:

1. 75x - 30 = 330

First, add 30 to both sides of the equation to isolate the term with "x":

75x - 30 + 30 = 330 + 30 75x = 360

Now, divide both sides by 75 to solve for x:

75x / 75 = 360 / 75 x = 4.8

So, the solution for the first equation is x = 4.8.

Now, let's solve the second equation:

2. 75*4 + x = 330

Multiply 75 by 4:

75 * 4 = 300

Now, we have the equation:

300 + x = 330

To solve for x, subtract 300 from both sides:

300 + x - 300 = 330 - 300 x = 30

So, the solution for the second equation is x = 30.

Now you have the solutions for both equations:

1. x = 4.8
2. x = 30

Answer 3

Let's solve this equation step by step:

75x - 30 = 330

First, we want to isolate the variable 'x' on one side of the equation. Start by adding 30 to both sides:

75x - 30 + 30 = 330 + 30

This simplifies to:

75x = 360

Now, we want to solve for 'x,' so divide both sides of the equation by 75:

(75x)/75 = 360/75

x = 4.8

So, the solution for the first equation is x = 4.8.

Now, let's address the second equation:

33075*4 + x = 330

First, simplify the left side:

33075*4 = 132300

So, the equation becomes:

132300 + x = 330

Now, isolate 'x' by subtracting 132300 from both sides:

132300 + x - 132300 = 330 - 132300

x = -131970

So, the solution for the second equation is x = -131970.
