Feb and March: 50$
April to Oct: 140$
=>1+50+140=191
<span>Simplifying
4x + -1y = 10
Solving
4x + -1y = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
4x + -1y + y = 10 + y
Combine like terms: -1y + y = 0
4x + 0 = 10 + y
4x = 10 + y
Divide each side by '4'.
x = 2.5 + 0.25y
Simplifying
x = 2.5 + 0.25y</span>
First term = 2(1) - 3 = 2 - 3 = -1
Answer:
x=2 1/4
Step-by-step explanation:
Let's swap it around so its 1/3(8x+3)=7
Now you multiply both sides by 3 to make it 1(8x+3)=21
That means its 8x+3= 21
Subtract both sides by 3 to get rid of it
Now you have 8x=18
Which equals to x= 18/8
Which equals 2 1/4
Well, first of all, you have to open up the bracket by multiplying what's outside by what's inside. Anyway;
3k-15=-16
Next, you have to collect the like terms and put them together. And the -15 becomes +15. So;
3k=-16+15
3k=-1
Next, you have to divide the both sides by 3. So;
3k/3=-1/3
k=-1/3
So your answer is -1/3. Hope i helped. Have a nice day.
