Answer :
Answer:
[tex]15x-6y=48[/tex]
Step-by-step explanation:
So we have the system of equations:
[tex]5x-2y=16\\15x-7y=51[/tex]
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:
[tex]3(5x-2y)=3(16)[/tex]
Multiply:
[tex]15x-6y=48[/tex]
And we're done!
Answer:
Step-by-step explanation:
-15x + 6y = -48
15x - 7x = 51
-x = 3
x = -3
5(-3) - 2y = 16
-15 - 2y = 16
-2y = 31
y = -15.5
(-3, -15.5)
