The product of a number and -7 gives seven times the sum of that number and -40. Find the number
Solution
Let the number be \"x\".
product of the number and \"-7\" = x * (-7)
which gives => -7x
sum of the number and \"-40\"
x + (-40) => x - 40
so we have product of a number and -7 gives seven times the sum of that number and -40
-7x = 7(x - 40)
-7x = 7x - 280
-14x = -280
x = 20
