y = 2x + 2
4x - y = -6

x = - 2, y = - 2

Step-by-step explanation:

Given the 2 equations

y = 2x + 2 → (1)

4x - y = - 6 → (2)

Substitute y = 2x + 2 into (2)

4x - (2x + 2) = - 6 ← distribute and simplify left side

4x - 2x - 2 = - 6

2x - 2 = - 6 ( add 2 to both sides )

2x = - 4 ( divide both sides by 2 )

x = - 2

Substitute x = - 2 into (1) and evaluate for y

y = 2(- 2) + 2 = - 4 + 2 = - 2

solution is x = - 2, y = - 2

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
