What is the solution set of the following system of equations?
5x - 3y - 10 = 0
x + y - 7 = 0
Solution:
We will use the elimination method to solve the system of linear equations.
Let 5x - 3y - 10 = 0 --- equation(1)
x + y - 7 = 0 --- equation(2)
Step 1: Multiply equation(2) by 5.
5x + 5y - 35 = 0 --- equation(3)
Step 2: Subtract equation(1) from equation(3).
(5x + 5y - 35 = 0) - (5x - 3y - 10 = 0)
8y = 25
y = 25/8
Step 2: Substitute the value of y in equation (2), we get
x + 25/8 - 7 = 0
x + (25 - 56)/8= 0
x = 31/8
What is the solution set of the following system of equations?
5x - 3y - 10 = 0
x + y - 7 = 0
Summary:
The value of x and y in the solution to the following system of equations 5x - 3y - 10 = 0; x + y - 7 = 0 is 31/8 and 25/8 respectively.
