diamondboy · Answer

for a) subtract 7 from both sides and for b) subtract 2 from both sides

anonymous · Answer

what do mean when you say to subtract from both sides?

anonymous · Answer

For A-    3x+7=20  (Subtract 7 From a side to get x by itself)
                   -7   -7
                  3x=13 (Divide by 3 to get x by itself)
                  3      3
                   x=  4/1
                      x=4
So the answer for A Is $$x =4$$

And for B.
-2x+2=20    (Isolate x)
       -2  -2
-2x = 18   (Divide by -2 to get x by itself)
   x = -9
So the answer for B is
$$x =-9$$
