Answer:
Step-by-step explanation:
Ok, this is a Linear equation so you need to find the result of k;
First you sum the two terms that include k
34k+38k=12
72k=12
Secondly, you separate the 72·K term by sending the 72 diving to the other side of the equation(remember if you have a number multiplying when yoy pass it to the other side of the equation you need to pass it dividing):
K=12÷72
Then you resolve the division:
K=[tex]\frac{12}{72}[/tex]
IF the problem requires it, you can simplify the number tex]\frac{12}{72}[/tex] diving both numbers by 4 and then by 3 so the final result is:
K=[tex]\frac{1}{6}[/tex]
