Question

-3(а+5)=5(а-2)уравнение

Answer 1

-3(а+5) = 5(a-2)
-3a -15 = 5a - 2
-8a = 13
8a = -13
a = - 5/13

Answer 2

-3(а+5)=5(а-2)
-3а-15=5а-10
-3а-5а=-10+15
-8а=5
а=-5/8

Answer 3

To solve the equation -3(a+5) = 5(a-2), we can start by simplifying the equation through distribution and simplification of terms. Let's go step by step:

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

Start by applying the distributive property:

-3 * a + (-3) * 5 = 5 * a + 5 * (-2)

Simplify the products:

-3a - 15 = 5a - 10

Next, let's group the terms with variables on one side and the constant terms on the other side:

-3a - 15 - 5a = -10

Combine like terms:

-8a - 15 = -10

Now, let's isolate the variable term by moving the constant term to the other side of the equation. We can do this by adding 15 to both sides:

-8a - 15 + 15 = -10 + 15

Simplify:

-8a = 5

Finally, divide both sides of the equation by -8 to solve for 'a':

-8a / -8 = 5 / -8

Simplify:

a = -5/8

Therefore, the solution to the equation -3(a+5) = 5(a-2) is a = -5/8.
