Ответ:
1. x = -a/6
2. x = 3/a
x = -6/a
Step-by-step explanation:
1. 4 = (6/a)x+5
subtract 5 from both sides
-1 = (6/a)x
divide by 6/a on both sides
x = -a/6
To make that last part simpler, you could think of it as first multiplying by a and then dividing by 6.
2. 7+2ax = 13
subtract 7
2ax = 6
divide by 2
ax = 3
divide by a
x = 3/a
3. -ax-20 = -14
add 20
-ax = 6
divide by -a
x = 6/-a = -6/a
