Answer:
The equation for the given maths problem is  $ 34 + $ 8x = $ 90  
Step-by-step explanation:
According to question : 
The Total amount spent on  cloths = $ 90 
The cost of a pair of jeans  = $ 34
The cost of each t-shirt pair = $ 8
The amount spent on t-shirt = $ 90 - $ 34 = $ 56
Let the number of t-shirt pair = x
So, $ 34 + $ 8x = $ 90 
Or,  $ 8x = $ 90 - $ 34
∴          x = 
Hence The equation for the given maths problem is  $ 34 + $ 8x = $ 90  Answer
