Step-by-step explanation:
7b+3-4b=3(b+4)
7b-4b+3=3(b+4) _Step 1: group like terms
3b+3=3(b+4)____Step 2: add the terms
3b+3=3b+12____ Step 3: expand 3(b+4) to 3b+12
3b+3-3=3b+12-3_Step 4: subtract 3 from both sides
3b=3b+9_______Step 5: simplify
3b-3b=3b+9-3b__Step 6: subtract 3b from both sides
0=9___________Step 7: simplify
