Question

3x-2y=4 and 4x+7y=8
Thanks

Answer 1

Question- 3x-2y=4
4x+7y=8
Ans- Tiryak guda karne par
8 (3x-2y) = 4 (4x+7y)
24x - 16y = 16x + 28y
Pakchantar karne par
24x -16x = 28y - 16y
8x = 12y
x/y = 12/8
x/y = 3/2 ans

Answer 2

3x−2y=4;4x+7y=8

Step: Solve3x−2y=4for x:

3x−2y+2y=4+2y(Add 2y to both sides)

3x=2y+4

3x3=2y+43(Divide both sides by 3)

x=23y+43

Step: Substitute23y+43forxin4x+7y=8:

4x+7y=8

4(23y+43)+7y=8

293y+163=8(Simplify both sides of the equation)

293y+163+−163=8+−163(Add (-16)/3 to both sides)

293y=83

293y293=83293(Divide both sides by 29/3)

y=829

Step: Substitute829foryinx=23y+43:

x=23y+43

x=23(829)+43

x=4429(Simplify both sides of the equation)

Answer:

x=4429 and y=829
