How do you solve the following system: $2 x + 3 y = 34, 5 x - 3 y = 29$ $2x + 3y = 34, 5x - 3y = 29$ ?

x=9; y= $\frac{16}{3}$ $16/3$

Explanation:

If both equations are added it would be

7x= 34+29=63

Thus x= 63/7=9. With x=9 the first equation would become

2(9) +3y=34
Or, 3y= 34-18= 16
thus y= $\frac{16}{3}$ $16/3$
