Question

Y=x-3,0,5x + y = 3;​

Answer 1

Ответ:

4

Пошаговое объяснение:

0,5x + x - 3 = 3

0,5x + x = 3 + 3

1,5x = 6

x = 6 : 1,5

x = 4

Answer 2

To solve the system of equations:

1. Y = x - 3
2. 5x + y = 3

You can use the method of substitution. First, we can express 'y' in terms of 'x' from the first equation:

From equation 1: y = x - 3

Now, substitute this expression for 'y' into the second equation:

5x + (x - 3) = 3

Now, solve for 'x':

6x - 3 = 3

Add 3 to both sides:

6x = 6

Now, divide by 6:

x = 1

Now that you have the value of 'x,' you can find the value of 'y' by substituting it back into the first equation:

y = x - 3 y = 1 - 3 y = -2

So, the solution to the system of equations is:

x = 1 y = -2

Therefore, the solution to the system is (1, -2).
