Question

6m+3=9m-15 3n -(5n-5)=35

Answer 1

6m+3=9m-15
6m-9m=-15-3
-3m=-18
3m=18
m=18:3
m=6

3n -(5n-5)=35
3n-5n+5=35
-2n=35-5
-2n=30
2n=-30
n=-30:2
n=-15

Answer 2

1) 6m+3=9m-15
6m-9m= -15-3
-3m= -18
3m=18
m=6

 2) 3n -(5n-5)=35
3n-5n+5=35
-2n=30
n= -15

Answer 3

To solve the equations, let's take them one by one:

1. 6m + 3 = 9m - 15

Let's simplify the equation by combining like terms:

3 = 3m - 15

Now, let's isolate the variable 'm' by moving all terms without 'm' to the other side:

3 + 15 = 3m

18 = 3m

To solve for 'm,' divide both sides of the equation by 3:

18/3 = 3m/3

6 = m

Therefore, the solution to the first equation is m = 6.

2. 3n - (5n - 5) = 35

Start by simplifying the expression inside the parentheses:

3n - 5n + 5 = 35

Combine like terms:

-2n + 5 = 35

Next, isolate the variable 'n' by moving the constant term to the other side:

-2n = 35 - 5

-2n = 30

To solve for 'n,' divide both sides of the equation by -2:

(-2n)/(-2) = 30/(-2)

n = -15

Therefore, the solution to the second equation is n = -15.

So the solutions to the given equations are m = 6 and n = -15.
