please simplify this for me and explain how you did it

Simplify means to remove parentheses () and put like terms together.

Since there are no parenthesis given, we simply combine like terms.

2a and 6a are like terms since they have the same literal coefficient, “a”.

3b and -7b are also like terms, with the same literal coefficient, “b”.

Combining both sets of like terms results in:

2a+6a = 8a

3b-7b = -4b

Therefore, the simplified form is:

8a-4b

Going further by find a common factor of the two terms such that it becomes

4(2a-b)

is no longer “simplifying” but “factoring”.

Question= 2a+3b+6a-7b

Solution=(2a+6a)+(3b-7b)

={(2+6)a}+{(3-7)b}

=8a+(-4)b

=8a-4b (Ans)

2a+3b+6a-7b => 2a+6a+3b-7b =>(2+6)a + (3-7)b => 8a -4b

2a + 3b + 6a – 7b

= 2a + 6a + 3b – 7b . . . <= do the sum for like terms

= 8a – 4b

Done

just do 2a + 6a = 8a

then 3b – 7b = -4b

which then = 8a – 4b

2a+6a = 8a.

3b-7b = -4b

So simplified is 8a-4b.

Just combine like terms.

8 a – 4 b

2a+3b+6a-7b

2a + 6a = 8a

3b – 7b = -4b

so it is 8a – 4b =]

2b – b + 8 + 2 = b + 10
