I just worked it out on a piece of paper. You subtract 12 from both sides and your left with 12=9 which is not true so you use 12≠9

Solve for a: b − 2a = c

vlada-n [284]

Answer:

$a=-\frac{c-b}{2}$

Step-by-step explanation:

Solving for the variable $a$ , given that :

$b-2a=c$

We can first start start by subtracting $b$ from both sides of the equation:

$-2a=c-b$

Now, we can divide both sides of the equation by the coefficient of $a$ , which would be $-2$ :

$a=\frac{c}{-2}-\frac{b}{-2}$

Applying the fraction rule $\frac{a}{c}\pm\frac{b}{c} =\frac{a\pm b}{c}$ :

$a=\frac{c-b}{-2}$

Then, apply the fraction rule $\frac{a}{-b} =-\frac{a}{b}$

$a=-\frac{c-b}{2}$

Lee and Lyn both invested their birthday money. Lee put his money in a savings account that earned 8% simple interest annually.

Lyn made a better investment.

Her money will grow quicker than Lee because the money grows by 8% annually, and then the next year 8% off of the new balance.

Lee's money will only grow by 8% from the original price.
