Question

problem job: after how many weeks will ari and kirl have the same amount of money in savings? solve through equations or using the provided graphing space. $5x + 100 = 10x + 40$

Explanation:

Step1: Isolate x terms

Subtract $5x$ from both sides.
$5x + 100 - 5x = 10x + 40 - 5x$
$100 = 5x + 40$

Step2: Isolate the constant term

Subtract 40 from both sides.
$100 - 40 = 5x + 40 - 40$
$60 = 5x$

Step3: Solve for x

Divide both sides by 5.
$\frac{60}{5} = \frac{5x}{5}$
$12 = x$

Answer:

12 weeks
