Answer: The answer is 9.3 if the coefficient is 10, but the answer is -80/3 if the coefficient is 3

Step-by-step explanation:

Let's solve your equation step-by-step.

3+90=10x

Step 1: Simplify both sides of the equation.

3+90=10x

(3+90)=10x(Combine Like Terms)

93=10x

93=10x

Step 2: Flip the equation.

10x=93

Step 3: Divide both sides by 10.

10x

Let's solve your equation step-by-step.

3x+90=10

Step 1: Subtract 90 from both sides.

3x+90−90=10−90

3x=−80

Step 2: Divide both sides by 3.

marin [14]

Answer:

In fifteen years, Alexis would have 9200. In twenty years she would have 9600

Step-by-step explanation:

10% for interest of 8000= 80.

80 (interest for one year) * 15 (fifteen years)= 1200

1200 plus the original amount is 9200.

80 (interest for one year) * 20 ( twenty years)= 1600

1600 plus the original amount is 9600
