Question

Match each equation with its correct solution...... ​

Answer 1

Explanation:

1) n+15=10

solution;

n+15= -10

when a positive sign(+) is crossing an equality sign it becomes a negative sign(-)

so, n= -10 -15

n= -25

2) n-13= -12

solution;

remember the rule i told you in number 1 that's the same rule we will use here

n= -12+ 13

n=1

you see so easy... lets continue

3) n\5= -1\5

now in this one there is a new rule which is; when you see two fractions and there is an equal two in between them you cross multiply... okay lets solve

n\5= -1\5

-1*5=n*5

the reason why i exchanged was because the unknown should always be at the left hand side....okay

n*5=-1*5

5n/5= -5/5

5 will divide 5 which is remaining n

5 divide 5 which is -1

so n = -1

4) -5n =1

this is not a fraction so we just take the -5 to 1 and no cross multiplication (they are whole numbers so they meet each other)okay...

so, n=1/-5

Answer 2

-25 + 15 = -10

1 - 13 = -12

-1 divided by 5 = -1/5

-5 multiplied by -1/5 = 1

The bold ones are the answers
