Question

2x=3y+9 4x=4-5y solve the system by addition method

Answer 1

Answer:

(2.59, -1.27)

Step-by-step explanation:

(2x=3y+9)(-2) --->   -4x = - 6y-18

                               4x = - 5y +4  

                                0  =  -11y -14

                                11y=  -14

                                  y = $-\frac{14}{11}$ = -1.27

2x=3($-\frac{14}{11}$)+9

x = 2.59
