Answer : (0.96, 2.53)
Given the below system of equations
x - y = -1.57 ------------- equation 1
x + y = 3.48------------- equation 2
To find the y intercept of the first equation, make x = 0
x - y = -1.57
when x = 0
0 - y = -1.57
-y = -1.57
y = 1.57
To find x, let y = 0
x - y = -1.57
x - 0 = -1.57
x = -1.57
Therefore, we have (-1.57, 1.57)
Second equation
x + y = 3.48
To find y, make x = 0
0 + y = 3.48
y = 3.48
To find x let y = 0
x + y = 3.48
x +0 = 3.48
x = 3.48
Therefore, we have (3.48, 3.48)
We will now graph the above points
Therefore, the solution of the system of the equation is
x = 0.96 and y = 2.53
(0.96, 2.53)
