find three solutions of the equation 8x-2y=3
Answers
three solutions of the equation 8x-2y = 3
put x = 0
8(0)-2y = 3
0-2y = 3
y = 3/-2 first equation....
second , put x = -1
8(-1)-2y = 3
-8 -2y = 3
-2y = 3+8=11
y = 11/-2 second equation ....
third , put x = 1
8(1)-2y = 3
8-2y = 3
-2y = 3-8 = -5
y = -5/-2
y = 5/2 third equation

Step-by-step explanation:
8x-2y=3
1) x=2
8×2-2y=3....1) put in eqn 1)....
16-2y=3. 8x-2×13/2=3
-2y=3-16. 8x-13=3
-2y=-13. 8x=3+13
y=-13/-2. 8x=16
y=13/2. x=16/8
x=2
2) x=1
8×1-2y=3....1). put in eqn 1)
8-2y=3. 8x-2×5/2=3
-2y=3-8. 8x-5=3
-2y=-5. 8x=3+5
y=-5/-2. 8x=8
y=5/2. x=8/8
x=1
3) x=4
8×4-2y=3.....1). put in eqn 1)
32-2y=3. 8x-2×29/2=3
-2y=3-32. 8x-29=3
-2y=-29. 8x=3+29
y=29/2. 8x=32
x=32/8
x=4
