Question

4x+9y=5 , -5x+3y=8





by elimination method​

Answer 1

Answer:

y = 1

x= -1

Step-by-step explanation:

4x+9y=5    (i)

-5x+3y=8    (ii)

from eq i

x =- 9y +5 /4

now

putting value of x in eq ii

-5(-9y+5/4) + 3y = 8

45y/4 -25/4+ 12y/4 = 8

45y -25+12y = 32+25

57y =57

y = 57/57

y = 1

putting y=1 in eq 1

4x+9*1=5

4x = 5-9

4x = -4

x = -4/4

x = -1
