Solve by the elimination method.
4x – 3y = 4
- 8x + y = -8
determine the solution of the system

(1, 0 )

Step-by-step explanation:

Given the 2 equations

4x - 3y = 4 → (1)

- 8x + y = - 8 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the term in x

8x - 6y = 8 → (3)

Add (2) and (3) term by term

(- 8x + 8x) + (y - 6y) = (- 8 + 8), that is

- 5y = 0 ⇒ y = 0

Substitute y = 0 into either of the 2 equations and solve for x

Substituting in (1)

4x - 3(0) = 4, that is

4x = 4 ( divide both sides by 4 )

x = 1

Solution is (1, 0 )

x = 1 & y = 0

Step-by-step explanation:

4x - 3y = 4 (1)

-8x + y = -8 (2)

(1)×2 8x - 6y = 8 (3)

(3)+(2) 8x+(-8x)-6y+y = 8+(-8)

-5y = 0

y = 0

suby=0into(3) 8x - 6(0) = 8

8x = 8

x = 1

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
