Question

Equations: -5n=1 n+15= (-10) n/5 = -1/5 n-13= -12 Solutions n= -25 n= -1/5 n= -1 n=1 Match each equation with it's solution

Answer 1

-5n = 1 : n = -¹/₅

n+15 = (-10): n = -25

n/5 = -1/5 : n = -1

n-13= -12: n = 1

Answer 2

-5n = 1 ⇒ n = -¹/₅

n+15 = (-10) ⇒ n = 25

n/5 = -1/5 ⇒ n = -1

n-13= -12 ⇒ n = 1

Explanation:

-5n = 1

÷(-5) ÷(-5)

n = -¹/₅

n + 15 = (-10)

-15 -15

n = -25

n/5 = -1/5

×5 ×5

n = -1

n - 13 = -12

+13 +13

n = 1
