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

7x+2-2=16-27x = 147x/7 = 14/7x = 2
7x + 2 = -4 7x + 2 - 2 = -4 - 2 7x = -6 7x/7 = -6/7 x = -6/7
x = 22/7
x=-7/13
7x + 2 = 3Subtract 2 from both sides:7x = 1Divide both sides by 7:x = 1/7 or about 0.143
