The system of equations are .
Observe the coefficient of each term are different, so the best method is Elimination using multiplication to solve the system of equations.
Elimination method:
----------(1)
----------(2)
To get two equations that contain opposite terms multiply the first equation by 8.
Add the equations to eliminate the x - variable and solve the equation.
The resultant equation is .
Divide each side by 7.
The value of substitute in either equation to find x.
First equation: .
Add 15 to each side.
Divide each side by 2.
The solution is .
