Question

5.(-3+2)-7.(5-4)

Answer 1

\(5\cdot\left(-3+2\right)-7\left(5-4\right)\)

\(=5\cdot\left(-1\right)-7\cdot1\)

\(=5\cdot\left(-1\right)+7\cdot\left(-1\right)\)

\(=-1\cdot\left(5+7\right)\)

\(=-12\)

Answer 2

5.(-3+2)-7.(5-4)

=5.(-1)-7.1

=(-5).1-7.1

=1.[(-5)-7]

=1.(-12)=-12

Answer 3

5(-3+2)-7(5-4) = 5.(-1)-7.1 = -12
