Question

3x + 4y= 18
x+ 2y = 8
solve this linear equation in 2 variables​

Answer 1

Answer:

y = 3

Step-by-step explanation:

take x = 8 - 2y from the eq.2 and put in eq.1

Answer 2

Answer:

x=8-2y

3(8-2y)+4y=18

24-6y+4y=18

24-2y=18

24-18=2y

2y=6

y=3

then

x=8-6

x=2 .

so the values are 2 and 3
