What is the solution of mc013-1.jpg?

i have attached a screenshot with the equation.

a = -5

explanation:

before we begin, remember the following:

-ve * -ve = +ve

+ve * +ve = +ve

-ve * +ve = -ve

+ve * -ve = -ve

now, for the given equation, we have:

- (5 - (a+1)) = 9 - (5 - (2a-3))

start by resolving the inner brackets, this will give:

- (5 - a - 1) = 9 - (5 - 2a + 3)

now, gather like terms in each bracket. this will give us:

- (4 - a) = 9 - (8 - 2a)

then, resolve the brackets on both sides, this will give us:

-4 + a = 9 - 8 + 2a

gather like terms:

-4 + a = 1 + 2a

subtract "a" from both sides:

-4 + a - a = 1 + 2a - a

-4 = 1 + a

finally, subtract "a" from both sides of the equation:

-4 -1 = 1 + a - 1

-5 = a

hope this : )

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

The correct answer is -3.9> -4.5 gucci playa
