Answer:
(-2, -3)
Step-by-step explanation:
y=2x + 1
y= 0.5x - 2
2x+1= 0.5x -2
1.5x= -3
x= -2
y= 2x+ 1
y= 2(-2)+1
y= -3
The solution is (-2,-3)
The solution to the set of simultaneous equations is; (-2, -3)
We are given the equations;
y = 2x + 1 ---(eq 1)
y = 0.5x - 2 ---(eq 2)
subtract eq 2 from eq 1 to get;
0 = 2x - 0.5x + 1 - (-2)
0 = 1.5x + 3
x = -3/1.5
x = -2
Thus;
y = 2(-2) + 1
y = -4 + 1
y = -3
