Answer:
y int (0, 13)
x int (-13/6,0)
just make the x = 0 and solve to get y
same with the x make y =0 and solve
 
        
             
        
        
        
Answer:
They both have the same slope. 
They have different y- intercepts.
They have no solution.

Check the picture below.
and since a triangle has a sum of 180° for all interior angles.
A = 180 - 39.34 - 25
A = 115.66

make sure your calculator is in Degree mode.
 
        
                    
             
        
        
        
There is actually 2 ways to solve this, I will show you both.
The first is obvious, solve for x in the first one, and plug it into the 2nd one and get the answer
4x + 7 = 12
4x = 5
x = 
8( ) + 3
) + 3
2 * 5 + 3
10 + 3
13
The 2nd option is to manipulate the 4x + 7 to be 8x + 3
4x + 7 = 12
start by moving the 7 over
4x = 5
multiply both sides by 2
8x = 10
and add 3 to both sides
8x + 3 = 13
