Answer:

The answer is k = 28

Step-by-step explanation:

\frac{12}{k}=\frac{18}{42}

Cross multiply. Remember, \frac{a}{b}=\frac{c}{d} ⇒ ad=bc

\frac{12}{k}=\frac{18}{42} ⇒ k·18=12·42

k·18=12·42

Simplify

18k=504

÷18 on both sides

k=504÷18

Simplify

k=28

5x − 3+ 2x = x + 7 + 6x
Masteriza [31]

Answer:

There isnt any solution.

Step-by-step explanation:

but these are the steps:

Step 1: Simplify both sides of the equation.

5x−3+2x=x+7+6x

5x+−3+2x=x+7+6x

(5x+2x)+(−3)=(x+6x)+(7)

7x+−3=7x+7

7x−3=7x+7

Step 2: Subtract 7x from both sides.

7x−3−7x=7x+7−7x

−3=7

Step 3: Add 3 to both sides.

−3+3=7+3

0=10
