- Solve 2m + n = 2 and 3m - 2n = 3 using substitution.

We can use the substitution method to solve linear equations of this form. Let's solve for m & n.

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

Choose one of the equations and solve it for m by isolating m on the left-hand side of the equal sign.

Subtract n from both sides of the equation.

Divide both sides by 2.

Multiply 1/2 times -n+2.

Substitute
for m in the other equation, 3m-2n=3.

Multiply 3 times
.

Add
to -2n.

Subtract 3 from both sides of the equation.

Divide both sides of the equation by
, which is the same as multiplying both sides by the reciprocal of the fraction.

Substitute 0 for n in
. Because the resulting equation contains only one variable, you can solve for m directly.

The system is now solved.

Answer:
The dimension of the rectangular pool is 
Step-by-step explanation:
Given : A rectangular swimming pool is three times as long as it is wide. If the perimeter of the soccer field is 300 yards.
To find : What are the dimensions?
Solution :
Let the width of the rectangular pool be 'x'.
A rectangular swimming pool is three times as long as it is wide.
The length of the pool be '3x'
The perimeter of the rectangular swimming pool is
The perimeter of the soccer field is 300 yards.
Substitute the value in the formula,
The width of the pool is x=37.5 unit
The length of the pool is 
Therefore, The dimension of the rectangular pool is
