Answer: There is no solution to the system of equations

Step-by-step explanation:

y + 7y = 3x ------(1)

6x - 2y = 12 -----(2)

from equation(1)

y = 3x - 7y -------(3)

substitute equation (3) in equation (2)

6x - 2(3x-7) =12

6x - 6x +14 = 12

0+ 14 = 12

Therefore there is no solution

Y + 7 = 3x.....y = 3x - 7

6x - 2y = 12
6x - 2(3x - 7) = 12
6x - 6x + 14 = 12
14 = 12 (incorrect)

when ur variables cancel out and u r left with an incorrect statement, this means there is no solution because ur lines are parallel

so ur answer is : no solution

Write a word problem for the equation. 1/2 (x-4) = 1/3x + 2

Ganezh [65]

Answer:

Half the age of Carlos four years ago is 2 years more than one-third his current age.

Step-by-step explanation:

We want to write a word problem for the equation.

$\frac{1}{2} (x - 4) = \frac{1}{3}x + 2$

Let x represent the present age of Carlos.

Four years ago, Carlos was x-4 years.

Half his age four years ago is ½(x-4)

Two years more than one-third his current age is ⅓x+2
