3X+2Y=82X+5Y=18please mark me ​

Answer»

Answer:

x=14.3

y=-17.5

Step-by-step explanation:

3x+2y=8

3x=8-2y

x=(8-2y)/3 equation 1

now PUT the VALUE of x in 2nd equation

2(8-2y)/3+5y=18

(16-4y)/3=18

16-4y=18×3

16-4y=54

-4y=54+16

-4y=70

y=70/-4

y=-17.5

now put the value of y in equation 1

x=[8-2(-17.5)]/3

x=(8+35)/3

x=43/3

x=14.3
