Which expression models the phrase “wally mowed two more lawns than he mowed last week”? n+2 n-2 2-n 2n

For this case we have to:

n: It's the variable that represents the number of lawns that mowed Wally last week.

If you tell us as a fact that this week Wally mowed two more lawns, then we have the following expression:

Finally, the expression is:

Option A

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
