Answer:
a:d=7:9
Step-by-step explanation:
We have a system with 3 equation:

If we multiply all of these equations, then we have:

If we simplify this fraction dividing by 9, then:

Therefore, a:d=7:9
Answer:
There are no solutions.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x/5+2/3+1x/5=x
4/5x+2/3+1/5x=x
(4/5x+1/5x)+(2/3)=x(Combine Like Terms)
x+23=x
x+23=x
Step 2: Subtract x from both sides.
x+2/3−x=x−x
2/3=0
Step 3: Subtract 2/3 from both sides.
2/3−2/3=0−2/3
0=−2/3
Answer:
There are no solutions.
