Answer:
x = 30
Step-by-step explanation:
Let's set up an equation to represent this problem:
2/5 * x + 15 = 27
subtracting 15 from both sides,
2/5 * x = 12
Multiplying 5/2 to both sides,
5/2 * 2/5 * x = 12 * 5/2
1*x = 30
x = 30
Answer:
Sara's number is 28
Step-by-step explanation:
Let's assign Sara's number the variable x and solve this equation using the information provided.
"If you subtract 14 from my number"
x - 14
"and multiply the difference by - 3"
-3(x - 14)
"the result is – 42."
-3(x - 14) = -42
Now we can solve from here for x.
-3(x - 14) = -42
x - 14 = 14
x = 28
