Answer:
![15x-6y=48](https://tex.z-dn.net/?f=15x-6y%3D48)
Step-by-step explanation:
So we have the system of equations:
![5x-2y=16\\15x-7y=51](https://tex.z-dn.net/?f=5x-2y%3D16%5C%5C15x-7y%3D51)
And we want to multiply the first equation by some constant such that the resulting equation matches the coefficient of [x] in the second equation.
We can see that the coefficient of x in the second equation is 15.
So, to match 15, we must multiply the first equation by 3. So:
![3(5x-2y)=3(16)](https://tex.z-dn.net/?f=3%285x-2y%29%3D3%2816%29)
Multiply:
![15x-6y=48](https://tex.z-dn.net/?f=15x-6y%3D48)
And we're done!
