Question

7b−​​​2/5​​=6b−7/5 solve for b ​​

Answer 1

So first you need to combine like terms:
7b -2/5 = 6b - 7/5
     +2/5        +2/5
7b = 6b -5/5
7b = 6b -1
-6b   -6b
b=-1

Answer 2

Let's solve your equation step-by-step.
7b−2/5=6b−7/5

Step 1: Simplify both sides of the equation.
7b+−2/5=6b+−7/5

Step 2: Subtract 6b from both sides.
7b+−2/5−6b=6b+−7/5−6bb+−2/5=−75

Step 3: Add 2/5 to both sides.
b+−2/5+2/5=−75+2/5
b=−1
Answer:b=−1
