Since 3x-5 is put to the absolute right after the math is finished and 8 is our answer we are looking for.
this one can be tricky
if we use -1
2|3*-1=-3-5=-8|
2*8 = 16
16-8 = 8
it would be -1.
The resulting equation will be x + y = 4 and 4y =20
<h3>System of equation</h3>
GIven the system of equation given as:
x + y = 4
-3x + y = 8
If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:
3x + 3y = 12
-3x + y = 8
Adding both equation
3y + y = 12 + 8
4y = 20
Hence the resulting equation will be x + y = 4 and 4y =20
