Do cross multiplication

  <u>6</u>  =  <u>x</u>
 18    12

Now cross multiply

(6)(12) = (18)(x)

       72 = 18x

Divide both sides by 18
     
    
     <u>72</u>  = <u>18x</u>
     18      18

      4   = x

So tMei can complete 4 problems in 12 minutes.

I need someone to solve this math problem by elimination for me. <br><br> 3X+2y=6<br> -x+y=-2
FinnZ [79.3K]
3x + 2y =   6 ⇒ -3x - 2y = -6
 -x +   y = -2 ⇒ <u>-3x + 3y = -6</u>
                                  <u>-5y</u> = <u>0</u>
                                   -5    -5
                                     y = 0
                         3x + 2(0) = 6
                             3x + 0 = 6
                           <u>        - 0 - 0</u>
                                   <u>3x</u> = <u>6</u>
                                    3     3
                                     x = 2
                              (x, y) = (2, 0)
