Question

4x+y=34;x+4y=16 सहगुना समान असताना

Answer 1

Answer:

$x = 8 \: \: \: \: \: y = 2.$

Step-by-step explanation:

$4x + y = 34 \: \: \: \: \: \: \: \: \: \: \: \: \: x + 4y = 16 \\ \\ 4x + y = 34 \: \: \: \: \: \: \: \: \: \: 4x + 16y = 64 \\ \\ 16y - y = 64 - 34 \\ \\ 15y = 30 \\ \\ y = 2 \\ \\ \\ therefore \: \: \: \: x = 16 - 4 \times 2 \\ \\ x = 16 - 8 \\ \\ x = 8.$

Answer 2

Answer:

x = 8 , y = 2

Step-by-step explanation:

4x+y = 34. (eq 1)

x+4y = 16 (eq 2)

• eq 2 x 4

(x+4y = 16) x 4 = 4x+16y = 64

• eq 2 – eq 1

4x+16y = 64

– 4x+ y = 34

• 15y = 30
• y = 15/30
• y = 2

Substituting y in eq 1

• 4x+(2) = 34
• 4x = 34 – 2
• 4x = 32
• x = 32/4
• x = 8
