The equivalent expression to 
<h3>What are the equivalent expressions?</h3>
Equivalent expressions are similar expressions that may have different forms but when a value is replaced with the variables in the same form provides the same answer.
From the information given, If:
- r(x) = 3x - 1
- s(x) = 2x + 1
Then the fractional form can be an expression as:

Answer/Step-by-step explanation:
Given:
m<EFH = (5x + 1)°
m<HFG = 62°
m<EFG = (18x + 11)°
Required:
1. Value of x
2. m<EFH
3. m<EFG
SOLUTION:
1. Value of x
m<EFH + m<HFG = m<EFG (angle addition postulate)
(5x + 1) + 62 = (18x + 11)
Solve for x using this equation
5x + 1 + 62 = 18x + 11
5x + 63 = 18x + 11
Subtract 18x from both sides
5x + 63 - 18x = 18x + 11 - 18x
-13x + 63 = 11
Subtract 63 from both sides
-13x + 63 - 63 = 11 - 63
-13x = -52
Divide both sides by -13
-13x/-13 = -52/-13
x = 4
2. m<EFH = 5x + 1
Plug in the value of x
m<EFH = 5(4) + 1 = 20 + 1 = 21°
3. m<EFG = 18x + 11
m<EFG = 18(4) + 11 = 72 + 11 = 83°
Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 10 to both sides
-6 (+10) = n/2 - 10 (+10)
10 - 6 = n/2
4 = n/2
Next, isolate the n. Multiply 2 to both sides
4(2) = n/2(2)
n = 4(2)
n = 8
8 is your answer
