Question

6×(0,5х-1,5)-4,5у+8=3(х-1,5у)-1

Answer 1

Ответ:

3x-9-4,5y+8=3x-4,5

3x-4,5y-3x=-4,5+9-8

-4,5x=-3,5

x=7/9;0,7

ответ:7/9;0,7

Answer 2

To solve the equation 6×(0.5x-1.5)-4.5y+8=3(x-1.5y)-1, follow these steps:

Step 1: Distribute the coefficients to simplify the equation.

6×(0.5x-1.5) becomes 3x - 9 3(x-1.5y) becomes 3x - 4.5y

Now the equation becomes: 3x - 9 - 4.5y + 8 = 3x - 4.5y - 1

Step 2: Combine like terms on both sides of the equation.

On the left side: (3x - 9) + 8 becomes 3x - 1

On the right side: (3x - 4.5y) - 1 remains the same.

The equation is now simplified to: 3x - 1 = 3x - 4.5y - 1

Step 3: Eliminate the "3x" term from both sides. Since it's the same on both sides, it cancels out.

You are left with: -1 = -4.5y - 1

Step 4: Isolate the "y" variable on one side by moving the other terms to the opposite side.

Add 1 to both sides: -1 + 1 = -4.5y - 1 + 1

Simplify: 0 = -4.5y

Step 5: Solve for "y" by dividing both sides by -4.5.

y = 0 / -4.5

y = 0

So, the solution to the equation is y = 0.
