Answer:
19
Step-by-step explanation:
Solving,
4x-5 = 27 add five to both sides
4x =32 divide by 4
x = 8 = blue marbles
3x-5 = 19 = red marbles.
Answer:
x = 48
Step-by-step explanation:
5x + 12 = 6x - 36 ( subtract 6x from both sides )
- x + 12 = - 36 ( subtract 12 from both sides )
- x = - 48 ( multiply both sides by - 1 )
x = 48

Answer: y=-3x/4 -1/4
Step-by-step explanation:
y=mx+b
-1=-3/4 * 1 +b
-1=-3/4 + b
(-1=-3/4 + b)*4
-4=-3+4b
4b=-1
b=-1/4
y=-3x/4 -1/4
The answer will be F^-1= x/4
