Question

Can you please help me answer this question 7n + 5 = 5n + 25

Answer 1

7n+5=5n+25  subtract 5n from both sides

2n+5=25  subtract 5 from both sides

2n=20  divide both sides by 2

n=10

Answer 2

Simplifying 7n+5=5n+25
 reorder the terms: 5 + 7n = 5n +25                                                                     combine like terms :7n + -5n =2n, 5 + 2n = 25 + 5n + -5n
combine like terms: 5n + -5n = 0, 5 + 2n = 25 + 0, 5 + 2n = 25
add -5 to each side of the equation : 5 + -5 + 2n + 25 + -5, 2n = 25 + -5
combine like terms  : 25 + -5 = 20 2n += 20

divide each side by 2

n=10
ANSWER: n = 10
