x-2y=14
x+3y =9
subtract the equations
x-2y = 14
-x-3y = -9
-5y = 5
divie both sides by -5
y = -1
substitute y = -1 into the first equation (or second)
x -2(-1) = 14
x + 2 = 14
x = 12
Solve using the quadratic formula
you do 3 plus 5 first then you get 8 you have to find out what minus 7 equals 8
15x minus 8=minus 180 3x+8=24
7
x = 25 / 3squared + 5
minus 5

X=1
By including its plus or minus signs
The solutions are: x = -2 and y = 4
7
x = 25 / 3squared + 5
It is an equation with the plus or minus signs missing which makes it impossible to solve.
