Answer:
x = -1
y = 4
Step-by-step explanation:
Solving system of linear equations by elimination method.
8x + 3y = 4 ---------------(I)
2x + y = 2 --------------(II)
Multiply the second equation by (-3) and then add them.Thus y will be eliminated and we will obtain the value of 'x'.
(I) 8x + 3y = 4
(II)*(-3) <u> -6x - 3y = -6 </u> {Now add}
2x = -2
x = -2/2

Plugin x = (-1) in any one of the equations. Here I have chosen equation (II)
2*(-1) + y = 2
-2 + y = 2
y = 2 + 2

Answer:
He paid $1.11
Step-by-step explanation:
2.50 * 0.4 (he paid for 40% of the original price, since it was a 60% discount) = 1
1 * 0.11 (11% sales tax) = 0.11
1 + 0.11 = 1.11
