2m + n = 2
3m - 2n = 3

m = 1   n = 0

Step-by-step explanation:

(2m + n = 2)2              You need to cancel out one of the variable, so I chose n

3m - 2n = 3

3m - 2n = 3            

4m + 2n = 4              Add the two equations together

7m = 7                       Divide both sides by 7

m = 1

Plug 1 in for m into one equation

2(1) + n = 2

2 + n = 2        

-2       -2                     Subtract 2 from both sides

n = 0

Check this with the other equation to make sure it is the same answer

3(1) -2n = 3

3 - 2n = 3

-3        - 3                    Subtract 3 from both sides

-2n = 0                        Divide both sides by -2

n = 0                          

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
