The cost of a shirt is $3 more than half the price of a pair of jeans. The cost of the shirt and jeans together is $45. Find the cost of each item.
OK, so I really struggle with math and I was hoping someone could help or explain this to me. And since I'm also in grade 9, we only use one variable.
When I tried it my equation ended up being x+(x÷2 [as a fraction] +3) but when I solved it I got $42. If you can help me that would be great!
