12 = 1.5x
Solve each equation algebraically

35

Step-by-step explanation:

I am assuming you want me to answer the equation provided in the picture, therefore I will provide you with the answer.

So we have = 21

When it comes to equations with a variable, our goal is to isolate the variable, so let's start.

= 21

1. Combine multiplied terms into a single fraction :

= 21

2. Multiply both sides by the denominator :

5 * 3/5 = 3

5 * 21 = 105

3x = 105

3. Divide both sides by 3 :

x = 35

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

the answer is 13 cm
