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 much did each eraser cost?​

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

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong
