As per the question, the first equation is -y+46=32
 
We can solve this equation by the steps below:
 
-y + 46 = 32
=> -y = 32-46
=>-y = -14
=> y = 14
 
Since it is a linear equation, only one solution exists, which is y = 14.
 
Similarly, the other equation can be solved as :
4x+3=2x+11
=> 4x-2x = 11-3
=> 2x = 8
=> x = 4
