Step-by-step explanation: A whole number is an integer or a number without fractions. Both 15% and 40% are less than 1 since they are less than 100%; therefore, it is impossible to express them as whole numbers. They can only be expressed as the mixed numbers of 0.15 and 0.4, or 15/100 and 40/100.
You have to distribute the 7 to x and 2 so : 7x+14=2x-1 Add one to both sides (inverse operations) 7x+14=2x-1 +1 +1 7x+15=2x Cross Cancel by subtracting 7x from both sides 7x+15=2x -7x -7x 15=-5x Divide by -5 15/-5= -5/-5 X= -3
