Answer:
b = 2
Step-by-step explanation:
In order to find the value of b, we have to isolate b on one side of equation first
So,

Multiplying 2 with b-1

Adding 2 on both sides

Dividing by 5 on both sides

So the value of b is 2 ..
X-y=34
x+y=338
We can use elimination in this problem.
2x=372
x=186
186+y=338
y=338-186
y=152
