Which expression is equivalent to (-1.3x-4.5) - (-2.1x+3.6)?

timurjin [86]

Equivalent expressions are expressions with the same value.

The equivalent expression of $(-1.3x - 4.5)- (-2.1x + 3.6)$ is $0.8x -8.1$

Given that:

$(-1.3x - 4.5)- (-2.1x + 3.6)$

Open brackets

$(-1.3x - 4.5)- (-2.1x + 3.6) = -1.3x - 4.5+ 2.1x - 3.6$

Collect like terms

$(-1.3x - 4.5)- (-2.1x + 3.6) = -1.3x + 2.1x - 4.5 - 3.6$

$(-1.3x - 4.5)- (-2.1x + 3.6) = 0.8x -8.1$

Hence, the equivalent of $(-1.3x - 4.5)- (-2.1x + 3.6)$ is $0.8x -8.1$
