The answer is 4. 3x4 - 1 =11 12 - 1 = 11
8x8 = 64 so it is 64 (the y) 3x4 = 12 so it is 12 (the x) 64+12 is 76.
The solution is: x = 1 and y = -1
There is one solution for x and one solution for y. The solution is: x = -1 ; y = 2
In the equations Y=X-1 and Y=-X+1, the solution is (1,0)
12
y = 1
-4
x=4 y=4
This is not a solution because of the following procedure shown below: y+1.1=4y-21.2 22.3=3y y=7.4333 Therefore, y=7.1 is not a solution for this equation.
x = 9 and y = 28
y=x+4
