Question

-2,95n+7+1,5=(10+1,5)−3,95n

Answer 1

-2.95n + 3.95 n =11.5-8.5
1n = 3
n =3:1
n =3

Answer 2

To solve the equation, let's first simplify the expressions:

Left-hand side (LHS): -2.95n + 7 + 1.5

Right-hand side (RHS): (10 + 1.5) - 3.95n

Now, combine like terms:

LHS: -2.95n + 8.5

RHS: 11.5 - 3.95n

Now, the equation becomes:

-2.95n + 8.5 = 11.5 - 3.95n

Next, we want to isolate the variable 'n' on one side of the equation. Let's move the term with 'n' to one side and the constant terms to the other side:

Add 2.95n to both sides:

-2.95n + 2.95n + 8.5 = 11.5 - 3.95n + 2.95n

Simplify:

8.5 = 11.5 - 1n

Now, we need to get rid of the constant term on the right side. To do that, subtract 11.5 from both sides:

8.5 - 11.5 = -1n

Simplify:

-3 = -1n

Finally, divide both sides by -1 to solve for 'n':

n = 3

So, the solution to the equation is n = 3.
