Answer:
63 yellow marbles
Step-by-step explanation:
You can set up this equation as a proportion:
7/5 = x/45
Divide 45 by 5 to see what 7/5 must be multiplied by to get to x/45.
You should get 9, so also multiply 7 by 9 to get this:
7/5 = 63/45
This shows that there are 63 yellow marbles for 45 green marbles.

We are given with two equations X + y = k and <span>x - y = k. to find the solution of the </span>system<span> of linear equations, we can use elimination by adding the equations to eliminate y. hence the third equation is 2x= 2k ; x = k, hence y is equal to zero. Answer is C</span>
