Answer:

1= 12

Step-by-step explanation:

Simplifying

l + (-3) = 9

l + -3 = 9

Reorder the terms:

-3 + l = 9

Solve

-3 + l = 9

Solve for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + l = 9 + 3

Combine like terms: -3 + 3 = 0

0 + l = 9 + 3

l = 9 + 3

Combine like terms: 9 + 3 = 12

l = 12

Simplifying

l = 12
