Question

6a-a-9a+5a= a+(4a+10)-(25+a) -3(b-6)+8(b-4)

Answer 1

Ответ:

6a-a-9a+5a=а

a+(4a+10)-(25+a)=а+4а+10-25-а=4а-15

-3(b-6)+8(b-4)= -3b+18+8b-32=5b-14

Answer 2

Let's simplify the given equation step by step:

6a - a - 9a + 5a = a + (4a + 10) - (25 + a) - 3(b - 6) + 8(b - 4)

Combining like terms on each side:

2a = a + 4a + 10 - 25 - a - 3(b - 6) + 8(b - 4)

Simplifying the expressions within parentheses:

2a = a + 4a + 10 - 25 - a - 3b + 18 + 8b - 32

Combining like terms:

2a = 4a - a + 8b - 3b + 10 - 25 + 18 - 32

Simplifying further:

2a = 3a + 5b - 29

To isolate the variable 'a', we'll subtract 3a from both sides:

2a - 3a = 3a + 5b - 29 - 3a

Simplifying:

• a = 5b - 29

Finally, to solve for 'a', we multiply both sides by -1:

a = -5b + 29

So the solution to the equation is a = -5b + 29.
