Answer 1

I can’t view the image files you attached. Could you please type the two equations from the system here?

If you want to proceed while you type them, here are two quick ways to solve a 2×2 linear system

1) If the system is
a1 x + b1 y = c1
a2 x + b2 y = c2

you can use Cramer’s-rule formulas:
x = (c1 b2 − b1 c2) / (a1 b2 − b1 a2)
y = (a1 c2 − c1 a2) / (a1 b2 − b1 a2)
(denominator must not be 0)

2) Elimination (step-by-step):
- Multiply one or both equations so the coefficients of x (or y) match in magnitude.
- Add or subtract the equations to eliminate that variable and solve for the remaining variable.
- Substitute back to get the other variable.

If you paste the actual equations I’ll compute the ordered pair (a, b) for you.
