Step-by-step explanation:
Answer:
b
Step-by-step explanation:
First, you need to add 4 to both sides so you’re left with 5/6x = 6
then, divide 6 by 5/6 to find x
for me personally, it help to write 6 as 6/1
cross multiply so both fractions have the same denominator
6 divided by 5/6 is 36/5 as a mixed number or 7 1/5
Answer:

Step-by-step explanation:
The expression is presented below:

The above represents an expression
1. You are trying to isolate "F" in the equation
Multiply 9/5 on both sides

Add 32 on both sides


THIS IS WRONG
2. You are trying to isolate "y" in the equation
Multiply 3 on both sides
3m = x + y + z Subtract x and z on both sides
3m - x - z = y
THIS IS CORRECT
3. Isolate "r"
Multiply (r - 1) on both sides
s(r - 1) = r Distribute s into (r - 1)
sr - s = r Subtract sr on both sides
-s = r - sr Factor out r from (r - sr)
-s = r(1 - s) Divide (1 - s) on both sides

THIS IS WRONG
4. Isolate "b"
Multiply 2 on both sides
2A = a + b Subtract a on both sides
2A - a = b
THIS IS CORRECT
5. Isolate "y"
Multiply 2 on both sides
2m = x + y Subtract x on both sides
2m - x = y
THIS IS WRONG
