The answer you are looking for is X = 17.

First, you would combine like terms (x and 3x) to get 4x. The equation would now say 4x + 4 = 72.

Next, you subtract 4 from both sides. Doing this cancels out the 4 on the left side of the equation, and leaves 68 on the right side.

Finally, you divide both sides by 4 (in order to get "x" by itself). Thus getting an answer of X = 17.

I hope this helps!

Generic sugar which costs $2.23/kg is made by combining brand X sugar which costs $1.18/kg with brand Y sugar which costs $3.98/

White raven [17]

Answer:

X = 14 kg

Y= 7 kg

Step-by-step explanation:

LET X and Y equal the amounts of brand X and Y

X = kg of brand X

Y = kg of brand Y

we know:

1) X + Y = 21 (kg)

2) 1X + 4Y = 2(X + Y) (This is the cost/kg * amounts for total cost)

Coefficients 1,4,2 are the cost/kg)

substitute eq. 1 (X+Y), = 21 into right side of equation 2

1X + 4Y = (21)*2

use elimination to solve 2 equations

X + Y = 21

X + 4Y = 42 (now subtract, note: I wrote the 1X as just X)

------------------

0 -3Y = -21 OR Y = 7 kg so X = (21-7) OR X = 14 kg
