Set them equal to each other because they are parallel
3x+7=5x-17
Subtract 3x from both sides
7=2x-17
Add 17 on both sides
24=2x
Divide by 2 on both sides
12=x
19.（3/4）/（1/32）=24
20.（3/4）/（1/14）=21/2
21.（1/2）/（1/72）=36
B. neither is a solution because 24-7 and 24-3 don’t come out to 20.
Answer:
-18
Explanation:
a - b
a = -7
b = 11
Insert -7 for 'a' and 11 for 'b'
-7 - 11
= -18
Answer:
x=b/(ay)
Step-by-step explanation:
To make x the subject of the formula, we basically have to isolate the x.
To do this we first multiply both sides by x.
xy=b/a
Now, to isolate the x, we simply divide by y,
x=b/(ay)
So x=b/(ay) is our answer
