Finish solving the system of equations β9.5x β 2.5y = β4.3 and 7x + 2.5y = 0.8 using the linear combination method.
1. Determine which variable will be eliminated: y will be eliminated because β2.5y and 2.5y are opposite terms.
2. Add the equations together to create a one-variable linear equation: β2.5x = β3.5
3. Solve to determine the unknown variable in the equation: x = 1.4
4. Substitute the value of the variable into either original equation to solve for the other variable.
The solution to the system is (
,
).
