Question

.Sovle the pair of linear equations 2x+3y+5=0 and 3x+4y+6=0 by using graph.​

Answer 1

Answer:

your answer

Step-by-step explanation:

2x+3y+5=0

2x+3y= -5 (1)

3x+4y+6=0

3x+4y= -6 (2)

multiply in eq (1) by 3

6x+9y= -15 (3)

multiply in eq (2) by 2

6x+8y= -12 (4)

subtract eq 3 and 4

y= -3

substitute y= -3 in eq 4

6x+8(-3)= -12

6x-24= -12

6x=12

x=12/6

x = 2

solution (2,-3)
