Question

Which is the best approximate solution of the system of linear equations y = 1.5x – 1 and y = 1

(0.33, 1)
(1.33, 1)
(1.83, 1)
(2.33, 1)

Answer 1

(1.33, 1)

Explanation:

It's B on ed

Answer 2

The answer is (1.33, 1)

We have a system of two equations:
y = 1.5x - 1
y = 1
________
Using the substitution method, we will substitute y from the second equation in the first equation:
1 = 1.5x -1
________
Now, we just need to solve for x:
1 + 1 = 1.5x
2 = 1.5 x
x = 2 / 1.5 = 1.33

Therefore, the solution is:
x = 1.33
y = 1
Or: (x, y) = (1.33, 1)
