Question$\begin{array}{l}0.8 x-2.1 y=10.8 \\ 1.6 x-0.7 y=7.6\end{array}$

Studdy Solution
Verify the solution $(x, y) = (3, -4)$ by substituting into the second original equation: $$1.6(3) - 0.7(-4) = 7.6$$ $$4.8 + 2.8 = 7.6$$ $$7.6 = 7.6$$ Since both original equations are satisfied, the solution is confirmed.
The solution to the system of equations is $x = 3$ and $y = -4$.
