Answer:
x = -7, y = 5
Step-by-step explanation:
a) x + 9y = 38, b) 3x + 7y = 14
From a)
x = 38 - 9y ---- (Equation 1)
From b)
{3*(38 - 9y)} + 7y = 14 ----- (From equation 1)
114 - 27y + 7y -14 = 0
100 - 20y = 0
20y = 100
y = 5
From a)
x + (9*5) = 38 (substituting the value of y = 5)
x + 45 = 38
x = 38 - 45
x = -7
Hope, this will help
Tax is:
$52* (2.9/100)= $1.51
$52+ $1.51= $53.51
The total cost (including tax) is $53.51~
