Question

86 - [ 15 x - 7 ( 6 x - 9 ) - 2 { 10 x - 5 ( 2 - 3 x ) } ]​

Answer 1

Answer:

3+77x answer✔️

Step-by-step explanation:

86−[15x−7(6x−9)−2{10x−5(2−3x)}]

=86−[15x−42x+63−2{10x−10+15x}]

=86−[15x−42x+63−20x+20−30x]

=86−15x+42x−63+20x−20+30x

Rearranging and collecting the like terms, we get:

=86−63−20−15x+42x+20x+30x

=3+77x
