(x-1)/(x+5) = 7/9
1. multiply both sides by (x+5)
x-1= 7/9 * (x +5)
2. multiply both sides by 9
9(x-1) = 7(x +5)
3. distribute the 9 and 7
9x – 9 = 7x +35
4. Add 9 to both sides
9x = 7x + 44
5. Subtract 7x from both sides
2x = 44
6. Divide both sides by 2 to get your final answer
x = 22

cross multiply, and regard x-1 as a unit, and x+5 as a unit. It looks like:
9(x-1) = 7(x+5)
can you finish it now?

(x-1)/ (x +5) = 7/9 —> just cross multiply
7(x+5) = 9(x-1) —-> distribute the equation
7x+35 = 9x-9
35+9 = 9x-7x
44 = 2x
x= 22
try to substitute the value you got to check if you got it right. =)
