Which value of x makes the following equation true? <br> 6(x - 1) = -2x + 50
lakkis [162]

Answer:

x=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6(x−1)=−2x+50

(6)(x)+(6)(−1)=−2x+50(Distribute)

6x+−6=−2x+50

6x−6=−2x+50

Step 2: Add 2x to both sides.

6x−6+2x=−2x+50+2x

8x−6=50

Step 3: Add 6 to both sides.

8x−6+6=50+6

8x=56

Step 4: Divide both sides by 8.

8x /8 = 56 /8

x=7

Answer:

The answer is Parson's Market.

Step-by-step explanation:

First you want to find out how much one pound costs.

For Parson's you take 11.34 and divide it by 6.

11.34 / 6 = 1.89

Then you take how many pounds you are trying to get (7) and multiply it by the price per pound (1.89)

7  * 1.89 = 13.23
