x+1+7x-3 Simplify adding the x terms and the numbers separately So it becomes x+7x+1-3 = 8x-2
3
Step 1. 7 = 7x +2 Step 2. subtract 2 from both sides: 7 - 2 = 7x + 2 - 2 and simplify: 5 = 7x Step 3. divide both sides by 7: (5/7) = (7x/7) and simplify 5/7 = x x = 5/7 or about 0.714285
i got 42 divided 7x
15xy-2xy-7x+x=13xy-6x
