You want to isolate the variable using the division property of inequality:
3x / 3 < -6 / 3 = x < -2. The sign of the inequality stays the same since you did not change the order of the inequality nor did you divide by a negative number on both sides. Hopefully this helps!

Given: Breakdown of Monthly Budget
Required
Determine the equation that shows minimum earnings in a year
First, we need to get the sum of the given list of budgets:
The are 12months in a a year; So, the yearly budget (y) is:
i.e.
Answer:
If you choose any value for k other than 6, that will be give you the one solution.
If k=6, you have no solutions because the lines will be parallel.
Step-by-step explanation:
We are going to put each of this in y=mx+b where m is the slope and b is the y-intercept.
kx+2y=5
Subtract kx on both sides:
2y=-kx+5
Divide both sides by 2:
y=(-k/2)x+(5/2)
The slope is -k/2 and the y-intercept is 5/2
3x+y=1
Subtract 3x on both sides:
y=-3x+1
The slope is -3 and the y-intercept is 1.
We want the system to have one solution so we want the slopes to be difference.
So we don't want (-k/2)=(-3).
Multiply both sides by -2: k=6.
We won't want k to be 6.
Answers are highlighted. All you really had to do was plug in your values of x back into the “y” equation. Peace!
