Answer 2

Simplifying the Expression

To simplify the given expression, let's expand and combine like terms step by step.

The given expression is: -5(3x+7-t)+(1.2a+3.4b+2)×3+-(4a-5b-3)

Expanding the expression: -5 * 3x - 5 * 7 + 5 * t + (1.2a + 3.4b + 2) * 3 - (4a - 5b - 3)

Simplifying further: -15x - 35 + 5t + 3.6a + 10.2b + 6 - 4a + 5b + 3

Combining like terms: (-15x - 4a) + (5t + 3) + (10.2b + 5b) + (-35 + 6)

Simplifying the expression gives us: -15x - 4a + 5t + 3 + 15.2b - 29

Therefore, the simplified expression is: -15x - 4a + 5t + 15.2b - 26

Answer

The simplified expression is -15x - 4a + 5t + 15.2b - 26.
