Respuesta :

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


Let's solve your equation step-by-step.
7b
2/5
=6b7/5

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+−7/56b
b+−2/5=−75

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