Substitute value of y from equation 1st into 2nd,
5x + 2y = 7
5x + 2(x - 7) = 7
5x + 2x - 14 = 7
7x = 7 + 14
x = 21 / 7
x = 3

Now, y = 3 - 7 = -4

In short, Your Answer would be Option B) (3, -4)

Hope this helps!

Josefina started to solve for x in the equation 3.5 = 1.9 – 0.8|2x – 0.6| using the steps below: 3.5 = 1.9 – 0.8|2x – 0.6| 1.6 =

She stopped because:
| 2 x - 0.6 | ≠ -2 . It is absolute value and it can´t be equal to the negative number.
This equation has no solution.
