1,98 : 4,5 = 0,7 -х 
0,44-0,7 = х 
х=0,26 

Answer 2

Solving the Linear Equation 1.98 - (0.7 - x) = 4.5

To solve the linear equation 1.98 - (0.7 - x) = 4.5, we can follow these steps:

1. Distribute the Negative Sign: Distribute the negative sign in front of the parentheses. 2. Combine Like Terms: Combine the constants and the variable terms. 3. Isolate the Variable: Isolate the variable term to solve for its value.

Let's go through these steps one by one.

Step 1: Distribute the Negative Sign

The equation 1.98 - (0.7 - x) = 4.5 can be rewritten as 1.98 - 0.7 + x = 4.5.

Step 2: Combine Like Terms

Combine the constants 1.98 and -0.7 to get 1.28. The equation becomes 1.28 + x = 4.5.

Step 3: Isolate the Variable

To isolate the variable x, we can subtract 1.28 from both sides of the equation: 1.28 + x - 1.28 = 4.5 - 1.28 x = 4.5 - 1.28 x = 3.22

Solution

The solution to the linear equation 1.98 - (0.7 - x) = 4.5 is x = 3.22.
