2(2x + 9) + 2(x) = 36
4x + 18 + 2x = 36
Combine like terms.
6x + 18 = 36
Subtract 18 from both sides.
6x = 18
Divide 6 on both sides.
x = 3
Hope this helps!
They are not
It goes from
0/0 1/3 2/5 3/6(or 1/2) which are not the same. This makes them not proportional to one another. (I think)
Known that,
x = z
Also known that,
x + y = 10
Substituting value of x,
z + y = 10
Hence, proved.
1/5( 1/2 + 1/3)
1/5 (3/6 + 2/6)
1/5(5/6)
5/30
1/6
Answer: I think it is -2.30
