Answer:
Sophie has 12.5 cards
Step-by-step explanation:
Let
x -----> number of cards Sophie has
y -----> number of cards Jackie has
we know that
x+y=30 -----> equation A
y=x+5 -----> equation B
Solve by substitution
Substitute equation B in equation A and solve for x
x+(x+5)=30
2x=30-5
x=12.5 cards
Note I assume the problem was invented without taking into account the result, because the amount of cards should be a whole number

2x=15+x
2x-x=15
x=15
In this case, we'll have to carry out several steps to find the solution.
Step 01:
data:
7x
Step 02:
We must analyze the equation to find the solution.
x = 29:
7 (29) = 203
The answer is:
203
So you have 4 red shirts out of (4+8) 12 total
