Question

Solve the equation by substitution method 2 X is equals to 5 Y + 4 and 3 X - 2 Y + 16 is equal to zero

Answer 1

Step-by-step explanation:

2X= 5Y + 4

X= 5Y + 4/ 2

putting value in eq 2

3 X-2Y = -16 .....ii

3(5Y+4/2) -2Y = -16

15Y + 12/2 -2Y = -16

15Y + 2 - 4Y = - 32

11Y = -34

Y = -34/11

putting value Y = -34/11 in eq 1

2X = 5 ( -34/11) +4

2X = -170/11 + 4

2X= -170 +44/11

X = -126/22
