5(x-3) = 2(x+3) solve for x
sattari [20]

Answer:

7

Step-by-step explanation:

5(x - 3) = 2(x + 3)                     Distribute

5x - 15 = 2x + 6                    

    + 15         + 15                     Switch sides to the liked terms

5x = 2x + 6 + 15

-2x  -2x                                   Switch sides to the liked terms

5x - 2x = 6 + 15  

<u>3x</u> = 21                                      Divide

3       3                  

x = 7

Clem Colfax had $10 to buy groceries. He needed milk costing 70 cents a carton, bread costing 60 cents a loaf, breakfast cereal
zaharov [31]
Cost of milk per carton = $ 70 cents = 70/100 = $0.7
Cost of bread per loaf = $60 cents = 60/100 = $0.6
Cost of cereals per box = $50 cents = 50/100 = $0.5
Cost of meat per pound = $1.50

If x is the number of cartons of milk bought, then
Number of loafs = x/2
Number pf boxes of cereals = x/2 +1
Number of pounds of meat = x/2 +1

Therefore,
0.7*x + 0.6*x/2 + 0.5 (x/2+1) + 1.5 (x/2+1) = 10
0.7x + 0.3x + 0.25x + 0.5 + 0.75x + 1.5 = 10
2x + 2 =10
2x = 8
x = 4

Substituting;
Milk cartons = 4
Number of bread = 4/2 = 2
Boxes of cereals = 2+1 = 3
Pounds of meat = 3
