3x + 2y = 6
2x + 3y = -1
You can use substition, elimation, or graphing to solve this system, but I prefer to use matrices. They are difficult to type out, but the answer is x = 4 and y = -3.
It is negative 5.
An equation where q = 240
Depends on the numbers. Whichever number is greater determines the sign for the equation.
b = 14
A negative plus a negative equals a negative.
It is negative 5.
3-(-9) Considering a negative plus a negative equals a positive your equation can be rewritten as 3+9 Which equals 12
-2x=2y-4 2x-y=-5 Answer=(-1,3)
A negative plus a negative equals a negative.
A suitable equation for that would be y is equal to negative 2 times x plus five
An equation where q = 240
Plugging the numbers into the equation gives b = -22.
negative 1
