Answer:
r=4
Step-by-step explanation:
Let's solve your equation step-by-step.
−4(r+2)=4(2−2r)
Step 1: Simplify both sides of the equation.
−4(r+2)=4(2−2r)
(−4)(r)+(−4)(2)=(4)(2)+(4)(−2r)(Distribute)
−4r+−8=8+−8r
−4r−8=−8r+8
Step 2: Add 8r to both sides.
−4r−8+8r=−8r+8+8r
4r−8=8
Step 3: Add 8 to both sides.
4r−8+8=8+8
4r=16
Step 4: Divide both sides by 4.
4r

Eli received the most votes
Step-by-step explanation:
Given percentages are:
Eli: 30%
Daphne: 27%
Celeste: 25%
Thaddeus: 18%
When a circle chart is used, the sum of all percentages is 100.
In case of finding the largest between the portions, the part with the greater percentage has the greater share in the chart.
According to given percentages, Eli has the highest percentage, which means that Eli received the most votes.
Hence,
Eli received the most votes

For this case we have the following equations:
2x - 3y = 1
2x + 3y = 2
When adding both equations we observe that:
Sentence 1: we have an equation of a variable, which in this case will be x. We can clear the value of x.
Sentence 2: Knowing the value of x, we can substitute in any equation and find the value of y.
Sentence 3: The value of x and y represents the point of intersection of both lines (x, y).
