Simplify the expression: 5(a+3)-4(3-2a)?

Question

Simplify the expression: 5(a+3)-4(3-2a)?

Answer 1

expand the expression

5(a+3)= 5a+15

4(3-2a)=12-8a

lets return to the original expression, then u replace it with the expansion

5(a+3)-4(3-2a)

= 5a+15-(12-8a)

=5a+15-12+8a

=13a+3 -------final answer!!!

Answer 2

5a + 15 -12 + 8a

then 5a + 8a = 13a

then 15-12=3

simplify so it will be...13a + 3

Answer 3

you have to combine like terms.  First multiply :

5(a+3) becomes 5a+15 and 4(3-2a) becomes 12-8a

so your probelm becomes

5a+15 - 12-8a, so you combine the 'a's 5a-8a=3a right?then15-12=3 you come out with 3a +3

simplification is not always simple, go one step at a time.

Answer 4

5a+15-12+8a

5a+8a=13a

15-12=3

13a+3  (final answer)

Answer 5

5a +15 - 12 + 8a

13a +3

Answer 6

5(a+3)-4(3-2a)=13a+3

Answer 7

5a + 15 - (12 - 8a )

5a  + 15 - 12 + 8a

13a + 3

Answer 8

5(a+3)-4(3-2a) When opening brackets you multiply the outer integer by all the integers in the bracket. Also note that a minus sign outside the bracket changes the signs inside the bracket thus minus becomes plus and vice versa.

=5a+15-12+8a Group like terms together

=5a+8a+15-12 Add and subtract accordingly

=13a+3----------Final answer!
