Answer 1

-0.4х+2.8+0.4х-1.8=1

ответ: 1

Answer 2

To solve the equation, follow these steps:

Step 1: Distribute the coefficients -0.4(x - 7) + 0.2(2x - 9)

Step 2: Simplify the equation by multiplying the coefficients with the terms inside the parentheses. -0.4x + 2.8 + 0.4x - 1.8

Step 3: Combine like terms (-0.4x + 0.4x) + (2.8 - 1.8)

Step 4: The x terms cancel out, and we're left with a constant term 0 + 1.0

Step 5: The result is 1.0.

So, the equation simplifies to 1.0:

1.0 = 1.0
