Answer:

N=-5

Step-by-step explanation:

N - 4 = 3n + 6

Add 4 to both sides

n-4+4=3n+6+4

Simplify

n=3n+10

subtract 3n from both sides

n-3n=3n+10-3n

Simplify

-2n=10

Divide -2 from both sides

-2n/-2=10/-2

Simplify

Ashley solved the equation for m using the following steps.

Natalka [10]

Answer:

Ashley should have added 4.5 to both sides.

Step-by-step explanation:

Given expression:

$-4.5+m=17$

Ashley's solution:

Subtracted 4.5 to both sides and got,

$m=12.5$

Correct solution:

Adding 4.5 to both sides.

$-4.5+m=17$

$+4.5$ $+4.5$

∴ $m=21.5$

Error made by Ashley was subtracting 4.5 both sides. Instead he should have added 4.5 both sides.
