Solve using substitution x = 3y + 1 2x + 4y = 12

Free_Kalibri [48]

Answer:

x = 4

y = 1

Step-by-step explanation:

x = 3y + 1 (Multiply everything by -2)

2x + 4y = 12 (Transfer 4y to the right of the = sign)

2x = -4y + 12

-2x = -6y - 2

0 = -10y + 10

-10 = -10y

y = 1

x = 3y + 1

x = 3(1) + 1

x = 3 + 1

x = 4

hjlf

Answer:

Option A. is correct.

Step-by-step explanation:

Given: A cell phone company recently noticed a $26\%$ sales decrease in the month of July compared to June such that $n$ represent June's sales.

Also, $y$ represents July's sales.

To find: equation that can be used to determine the sales in July

Solution:

June's sales $=n$

Decrease in sales $=\frac{26}{100}n=0.26n$

So,

July's sales $=n-0.26n$

Also,

July's sales $=y$

Therefore,

$y=n-0.26n$

So, option A. is correct.
