Step-by-step explanation:
Given equations: 
Divide 2 on both sides of equation (1) and 4 on the both sides of equation (2), we get

Adding equation (3) and (4), we get

Substitute x=5 in equation (4), we get

Hence, the solution of the both equations is (5,2).
Answer: True for all <em>b</em>.
Step-by-step explanation: To tangent a equation, find if the variable is true.
1. Add 56 to both sides.
63b - 56 + 56 = 63b - 56 + 56 = 7
2. Simplify.
63b = 63b
3. Simplify again for your answer.
0 = 0
Hence, both sides are equal.
