5. solve by substitution:
4x + y = 11
y = 3x - 3

(2, 3 )

Step-by-step explanation:

Given the 2 equations

4x + y = 11 → (1)

y = 3x - 3 → (2)

Substitute y = 3x - 3 into (1)

4x + 3x - 3 = 11, that is

7x - 3 = 11 ( add 3 to both sides )

7x = 14 ( divide both sides by 7 )

x = 2

Substitute x = 2 into (2) for corresponding value of y

y = (3 × 2) - 3 = 6 - 3 = 3

Solution is (2, 3 )

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
