Step-by-step explanation:
First, let's move the to the right-hand side so we can determine what constant we'll need on the left-hand side to complete the square:
From here, since the coefficient of the term is , we know the square will be (since it's half of ).
To complete this square, we will need to add to both sides of the equation:
Now we can take the square root of both sides to figure out the solutions to :
Answer:
m = 21
n= 25
Step-by-step explanation:
the equations are:
n + m= 46
5m-30 = 3n
