Estimate the solution to the system of equations.

Leona [35]

Answer:

$\sf C) \ x = -1\dfrac{2}{5} , \ y = \ 1\dfrac{3}{5}$

Given equations:

a) -3x + 3y = 9

b) 2x - 7y = -14

<u>Make x the subject in equation 1</u>:

-3x + 3y = 9

-3x = 9 - 3y

x = y - 3

<u>Substitute this into equation 2</u>:

2(y - 3) - 7y = -14

2y - 7y = -14 + 6

-5y = -8

y = -8/-5

y = 1.6

Then x = y - 3

= 1.6 - 3

= -1.4

Solution: (x, y) ⇒ (-1.4, 1.6)
