Part A: Charlie's answer is incorrect In step 2 of Charlie's answer he subtracted 5 from each side. Since 5x is multiplication, he must DIVIDE each side by 5 to get x by itself. The problem should have worked out like this...
Step 1: 5x = 30 Step 2: x = 30/5 Step 3: x = 6
Part B: There is only 1 solution for this problem.
