5.4-1.5х=0.3х-3.6. х=25

2х=18-х. х=6

Answer 3

It seems like you have a system of equations that you'd like to solve. Let's work through it step by step.

The given system of equations is:

1. 5.4 - 1.5x = 0.3x - 3.6
2. 2x = 18 - x

Let's start by solving equation (2) for x:

2x = 18 - x

Now, let's add x to both sides of the equation to isolate the variable on one side:

2x + x = 18

This simplifies to:

3x = 18

Now, divide both sides by 3 to solve for x:

x = 18 / 3 x = 6

Now that we have the value of x, let's substitute it into equation (1) to find the value of y:

5.4 - 1.5x = 0.3x - 3.6

Substitute x = 6 into the equation:

5.4 - 1.5(6) = 0.3(6) - 3.6

Now, calculate the values:

5.4 - 9 = 1.8 - 3.6

-3.6 = -1.8

Now, add 1.8 to both sides:

-3.6 + 1.8 = -1.8 + 1.8

-1.8 = 0

So, the solution to the system of equations is x = 6 and y = 0.
