Question

4x + 5 = 1,5,8х + 10 y = 3;​

Answer 1

Ответ:

Пошаговое объяснение:

4x=1.5-5

2 x 1,5-5+y=0

3 - 5 +y = 0

-2+y = 0

y = 2

Answer 2

It seems like you have a system of two linear equations. Let's solve this system for x and y. Here are the equations:

1. 4x + 5 = 1.5
2. 8x + 10y = 3

First, let's solve equation (1) for x:

4x + 5 = 1.5

Subtract 5 from both sides:

4x = 1.5 - 5 4x = -3.5

Now, divide both sides by 4 to isolate x:

x = -3.5 / 4 x = -0.875

Now that we have found the value of x, we can substitute it into equation (2) to solve for y:

8x + 10y = 3 8(-0.875) + 10y = 3

Now, calculate:

-7 + 10y = 3

Subtract -7 from both sides:

10y = 3 + 7 10y = 10

Now, divide both sides by 10 to isolate y:

y = 10 / 10 y = 1

So, the solution to the system of equations is:

x = -0.875 y = 1
