Answer 1

Пошаговое объяснение:

решить решить относительно y x

Answer 2

To solve the system of equations:

Equation 1: 3.2x + y - 5 = 0 Equation 2: 0.38x - 1.8y - 2 = 0

We can solve this system of equations using the method of substitution or elimination. Let's use the method of substitution:

Step 1: Solve Equation 1 for y: 3.2x + y - 5 = 0 y = -3.2x + 5

Step 2: Substitute the value of y in Equation 2: 0.38x - 1.8(-3.2x + 5) - 2 = 0

Step 3: Simplify and solve for x: 0.38x + 5.76x - 9 - 2 = 0 6.14x - 11 = 0 6.14x = 11 x = 11 / 6.14 x ≈ 1.79

Step 4: Substitute the value of x back into Equation 1 to solve for y: y = -3.2(1.79) + 5 y ≈ -3.42 + 5 y ≈ 1.58

Therefore, the solution to the system of equations is approximately x ≈ 1.79 and y ≈ 1.58.
