Question

9x-2y=-7 and 3x+5y=4 by elimination

Answer 1

Step-by-step explanation:

according to elimination

9x-2y=-7_eq 1 *(5)

3x+5y= 4_eq2 *(2)

45x-10y=-35+6x-10y=8

=52x=27

x=27/52

x=9/14

because -10y+10y cancelled out so this x valve put in eq_1

9x-2y=-7

9(9/14) -2y=-7

81-28y=-7

y= 88/28

y=11/14
