Write the equation for the word problem and solve. You bought a magazine for $5 and four erasers. You spent a total of $25. How
nikitadnepr [17]

Answer: each eraser cost 5 dollors                

Step-by-step explanation: Simplifying

25 = 5 + 4e

Solving

25 = 5 + 4e

Solving for variable 'e'.

Move all terms containing e to the left, all other terms to the right.

Add '-4e' to each side of the equation.

25 + -4e = 5 + 4e + -4e

Combine like terms: 4e + -4e = 0

25 + -4e = 5 + 0

25 + -4e = 5

Add '-25' to each side of the equation.

25 + -25 + -4e = 5 + -25

Combine like terms: 25 + -25 = 0

0 + -4e = 5 + -25

-4e = 5 + -25

Combine like terms: 5 + -25 = -20

-4e = -20

Divide each side by '-4'.

e = 5

Simplifying

e = 5

Ben is 12 years older than Ishaan. Ben and Ishaan first met two years ago. Three years ago, Ben was 4 times as old as Ishaan.
bixtya [17]
So, the 2 equations would be.... B -12 = I   and    (B - 3) = 4(I - 3)  the second sentence is irrelevant.
B - 3 = 4 (I) - 12
B - 3 = 4B - 48 - 12
B - 4B = -60 + 3
-3B = -57
B (Ben) = 19
Ishaan is 7

Hope this helps!
