The equation `2=7+b/4` has to be solved.
`2=7+b/4`
Subtract 7 from both the sides
`2- 7 = 7 + b/4 - 7`
=> `-5 = b/4`
Multiply both sides by 4
=> `-5*4 = (b/4)*4`
=> `-20 = b`
The solution of the equation is `b =-20`

2 = 7 + b/4
To find out the value of the variable b it must be isolated,
2 = 7 + b/4
2 - 7 = 7 + b/4 - 7 Subtract 7 from both sides
-5 = b/4
-5 * 4 = b/4 * 4
-20 = b
b = -20 Answer
You can verify the answer by inputting the value in the equation above.

The value of b has to be determined that satisfies 2=7+b/4.
Isolate b to one side of the equation and the numeric terms to the other side.
2=7+b/4
Add -7 to both the sides
2 - 7 = 7 - 7 + b/4
-5 = b/4
Multiply both sides by 4
-5*4 = 4*(b/4)
-20 = b
The required solution of the equation 2=7+b/4 is b = -20

QUESTION:-
Solve this equation
2=7+b/4
SOLUTION:-
The equation to be solved;
Transfer 7 to LHS and change its sign;
`2=7+b/4`
`2 - 7 = b/4`
`-5=b/4`
`Multiply(4*(-5))`
`-20=b`
`b=-20`
Hence the answer is b=-20
