Multiply the first equation by 7, then add the two equations.
78y = 546
Solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
2x + 10y = 58
-14x + 8y = 140
