Answer:

Step-by-step explanation:
Use the x-swap-y method to find the inverse:

-3/5x + 1/5 > 7/20
-3/5x > 7/20 - 1/5
-3/5x > 7/20 - 4/20
-3/5x > 3/20
x < 3/20 * - 5/3
x < -15/60 reduces to -1/4
Answer:
x=4
Step-by-step explanation:
4x-3=5x-7
-1x-3=-7 Subtract the 5x on both sides
-1x=-4 Add the -3 to the -7
x=4
