Question

Y=2x-1y=1,5+1y=0,2x-1y=2x-4​

Answer 1

Вроде правильно. Там где есть х в выражении решать дальше не получится, и нужно оставлять так как есть

Answer 2

It looks like you have a system of three linear equations in two variables, y and x. To solve for the values of x and y that satisfy all three equations, you can use various methods, such as substitution, elimination, or matrices.

Let's use the substitution method to solve this system of equations:

1. Start with the first equation: y = 2x - 1

2. Substitute this expression for y into the second equation: 1.5 + 1y = 0 1.5 + 2x - 1 = 0

3. Simplify the equation: 2x + 0.5 = 0

4. Subtract 0.5 from both sides of the equation: 2x = -0.5

5. Divide both sides by 2 to solve for x: x = -0.5 / 2 x = -0.25

Now that we have found the value of x, let's substitute it back into the first equation to find the value of y:

y = 2x - 1 y = 2(-0.25) - 1 y = -0.5 - 1 y = -1.5

So, the solution to the system of equations is: x = -0.25 y = -1.5
