X equals 6 because if you divide both sides by 4, move constant to the right, add the numbers, and divide both sides by 2. You end up with 6
I don’t understand the question u are asking
U is 10. If you subtract 11 first to get the variable and it's coefficient on its own, you see that 3u=30. To get the u on its own, you divide both sides by three. This gives you u=10
Well I think I can help you out ...
if you assume input x=2
the output will be as following :
y= -1/3(2)+2
=-2/3+2
=-2/3+6/3
=(-2+6)/3
=4/3
=1.333
