Answer:
b = 6
Step-by-step explanation:
Step 1: Write equation
-2.6b + 4 = 0.9b - 17
Step 2: Solve for b
Add 2.6b on both sides: 4 = 3.5b - 17
Add 17 on both sides: 21 = 3.5b
Divide both sides by 3.5: b = 6
Step 3: Check
Plug in x to verify if it's a solution.
-2.6(6) + 4 = 0.9(6) - 17
-15.6 + 4 = 5.4 - 17
-11.6 = -11.6
