Multiply the top equation by 6 and the bottom equation by 7. You will cancel x first by doing this and solve for y. You should get y=-1.
Substitute in y for either original equation.
You should get x=1.
Solution is (1,-1).

Answer:
It would take approximately 6.50 second for the cannonball to strike the ground.
Step-by-step explanation:
Consider the provided function.

We need to find the time takes for the cannonball to strike the ground.
Substitute h(t) = 0 in above function.

Multiply both sides by 10.

For a quadratic equation of the form
the solutions are: 
Substitute a = -49, b = 305 and c=88

Ignore the negative value of t as time can't be a negative number.
Thus,

Hence, it would take approximately 6.50 second for the cannonball to strike the ground.
