3x+4>13\times 7
Multiply both sides by 7. Since 7 is positive, the inequality direction remains the same.
3x+4>91
Multiply 13 and 7 to get 91.
3x>91-4
Subtract 4 from both sides.
3x>87
Subtract 4 from 91 to get 87.
x>\frac{87}{3}
Divide both sides by 3. Since 3 is positive, the inequality direction remains the same.
x>29
Divide 87 by 3 to get 29.
