Question

Twice a number plus 6 times the number is 72

Answer 1

Answer:

9

Step-by-step explanation:

Let the no be x

By the conditions given ,

2x + 6x = 72

8x = 72

x = 72/8

x = 9

therefore the no is 9

Answer 2

$(2 \times x) + (6 \times x) = 72 \\ 2x + 6x = 72 \\ 8x = 72 \\ x = 72 \div 8 \\ x = 9$
