If you would like to know in which step did the student first make an error and what is the correct step, you can calculate this using the following steps:

3(2x - 4) = 8 + 2x + 6
6x - 12 = 8 + 2x + 6
6x - 12 = 14 + 2x ... Step 2
6x - 2x = 14 + 12
4x = 26
x = 26/4 = 13/2

The correct result would be Step 2; <span>6x - 12 = 14 + 2x.</span>

The sum of two numbers is 48.<br>the second number is seven times the first number​
dusya [7]

Answer:

\huge\boxed{\sf x =6,\ y = 42}

Step-by-step explanation:

Let the numbers be x and y

<h3>Given condition:</h3>

x + y = 48 --------(1)

y = 7x -------------(2)

Put Eq. (2) in (1)

x + 7x = 48

8x = 48

Divide 8 to both sides

x = 48/8

<h3>x = 6</h3>

Put x = 6 in Eq. (2)

y = 7 (6)

<h3>y = 42</h3>

\rule[225]{225}{2}
