Question

Solve 7x + 8y = 23, 3x + 7y = 22❓​

Answer 1

Answer:

7x+8y=23___eq 1

3x+7y=22____eq 2

Multiply eq 1 with 3 and eq 2 with 7 on both sides

21x+24y=69 __eq 3

21x+49y=154 __eq 4

subtract above equations

-25y=-85

y= -85/-25

y=17/5 put in equation 3

21x+24(17/5)=69

21x+408/5=69

21x=69-408/5

taking LCM

21x=345-408/5

21x=-63

x= -63/21

x= -3

so,

x= -3 and y=17/5
