 Question 269235: Write inequality, solve problem, check solution. three times the sum of a number and seven is greater than five times the number minus 13 3(x)+7>5(x)-13 (is this right) How do I solve?Answer by dabanfield(803)   (Show Source): You can put this solution on YOUR website!Write inequality, solve problem, check solution. three times the sum of a number and seven is greater than five times the number minus 13 3(x)+7>5(x)-13 (is this right) How do I solve? Not quite right :) 3(x+7) > 5x - 13 Expanding we have: 3x + 21 > 5x - 13 Substract 3x from both sides: 3x - 3x + 21 > 5x - 3x - 13 21 > 2x - 13 Add 13 to both sides: 21 + 13 > 2x - 13 + 13 34 > 2x Divide both sides by 2: 34/2 > x x < 17
