ANSWER: 7/6
step 1: Simplify both sides of the equation.
step 2:Subtract 2/3 from both sides.
step 3: Multiply both sides by 7/(-1).
Answer:
<h2>.The last Opinion</h2>
Step-by-step explanation:
<h2>30s + 15c = 180</h2><h2>10s + 20s = 90</h2>
Answer:

Step-by-step explanation:
The two equations given represent two straight lines in 2-D graph.
The two lines will not intersect if they are parallel.
Hence the two equations will not have solution if the lines are parallel and not coincident.
The condition for 2 lines given by the equations :
ax+by+c=0
dx+ey+f=0 to be parallel but not coincident is:

here a=2 b=-3k c=-1 d=4 e=k+2 f=-5

But also:

Hence the value of k is -2/7.
