<span>Simplifying 5x + 2y = 9 Solving 5x + 2y = 9 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2y' to each side of the equation. 5x + 2y + -2y = 9 + -2y Combine like terms: 2y + -2y = 0 5x + 0 = 9 + -2y 5x = 9 + -2y Divide each side by '5'. x = 1.8 + -0.4y Simplifying x = 1.8 + -0.4y Hope i helped :)</span>

Person A can make a cupcake in 5 minutes, Person B can make a cupcake in 9 minutes. In total they made 168 cupcakes. How many cu
Stolb23 [73]

Answer:

Person A made 108 cupcakes and person B made 60 cupcakes.

Step-by-step explanation:

Person A makes 1 cupcake in 5 minutes.

Say in x minutes A makes : \frac{x}{5} cupcakes

Person B makes 1 cupcake in 9 minutes.

Say in x minutes B makes : \frac{x}{9} cupcakes

Total cupcakes prepared by A and B in x minutes = 168

\frac{x}{5}+\frac{x}{9}=168

\frac{14x}{45}=168

x=\frac{168\times 45}{14}=540

So, cupcakes made by A = \frac{540}{5}=108

Cupcakes made by B = \frac{540}{9}=60

Person A made 108 cupcakes and person B made 60 cupcakes.
