4(x+7)=38
4x + 28 = 38 - distribute the 4 into x and 7
4x = 10 - subtract 28 from both sides
x = 2.5 - divide both sides by 4 to get x by itself
answer - x = 2.5
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
