Answer:

no solution.

Step-by-step explanation:

1. 7x + 3 = 7x - 4             Subtract 7x on both sides

2. 3 = -4  

Three does not equal to negative four so, it has no solutions

Answer:

15x-6y=48

Step-by-step explanation:

So we have the system of equations:

5x-2y=16\\15x-7y=51

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)

Multiply:

15x-6y=48

And we're done!
