What you do to on side of an equation (=) you must do to the other to keep both sides equal.
r3-2+2=+2 (add 2 to both sides of the equation to simplify the left side)
which becomes
r3=2
r3/3 = 2/3 (divide both sides by 3) Note 3/3 =1 and 1 r is the same as r
which becomes
r=2/3 .

Step-by-step explanation:
Last year, the world produced 3.5 billion tons of cement and that amount could increase by a billion tons by the year 2050.
So, the net production of cement by the year 2050 will be (3.5 + 1) = 4.5 billion tons i.e.
tons. (Answer)
Now, this amount is larger than
by
times. (Answer)
