Question

(3x+6)+(12-2x) (8a+3b)+(5a-3b)

Answer 1

Ответ:

1) 3x+6+12-2x=0

x+18=0

x=0-18

x=-18

2)8a+3b+5a-3b=0

13a=0

a=0/13

a=0

Answer 2

To simplify the given expressions, we'll combine like terms. Let's simplify each expression step by step:

1. (3x + 6) + (12 - 2x) When adding these expressions, we group the like terms together: = 3x + (-2x) + 6 + 12 = x + 18

2. (8a + 3b) + (5a - 3b) Again, let's group the like terms: = 8a + 5a + 3b + (-3b) = 13a

Therefore, the simplified expressions are:

1. (3x + 6) + (12 - 2x) = x + 18
2. (8a + 3b) + (5a - 3b) = 13a
