From the graph, the solution of the first equation, x = 0.6 or - 3.6.
The solution of the second equation is, x = 0.8 or - 1.2
How to find the solution of the function?
The solution of the system of equation is determined by applying the following method.
The given function
y = x² + 3x - 2 ------- (1)
y = 3x² + x - 3 -------- (2)
when x = 0, the value of y is calculated as;
y = 0 + 0 - 2 = - 2
y = 0 + 0 - 3 = - 3
when x = 1, the value of y is calculated as;
y = (1²) + 3(1) - 2 = 2
y = 3(1²) + (1) - 3 = 1
when x = 2, the value of y is calculated as;
y = (2²) + 3(2) - 2 = 8
y = 3(2²) + (2) - 3 = 11
From the graph, the solution of the first equation, x = 0.6 or - 3.6.
The solution of the second equation, x = 0.8 or - 1.2
