Solving the system of equations
we get x=5 and y=10.5
Step-by-step explanation:
We need to solve the system of equations by substitutions.
The system of equations given are:

Let:

Putting value of y from eq(2) into eq(1)

So, value of x=5
Now putting value of x in eq 1 to find value of y:




So, value of y is 10.5
Solving the system of equations
we get x=5 and y=10.5

First you multiply both sides by 10, add 40, divide by 4, then square root
10*(4x^2-40/10)= (36)*10
(4x^2-40)+40=(360)+40
(4x^2)/4=(400)/4
x^2=100
x=10
