Объяснение:
Simplifying both sides of the equation, we get:
-5y + 20 - 4y + 9x - 4/8 + 1 = -4.5y + 4x + 18 - 0.5 + 1
Combining like terms, we have:
-9y + 20 + 9x - 1/2 = -4.5y + 4x + 19.5
Now, let's get rid of the fractions by multiplying everything by 2:
-18y + 40 + 18x - 1 = -9y + 8x + 39
Simplifying further, we get:
-18y + 18x + 39 = -9y + 8x + 39
Moving all variables to one side and constants to the other side, we have:
-18y + 9y + 8x - 18x = 0
Simplifying again, we get:
-9y - 10x = 0
So, the simplified equation is -9y - 10x = 0.
