5x – 1 = 3x – 15
Subtraction Property of Equality (Subtract 3x from both sides)
2x - 1 = -15
Addition Property of Equality (Add 1 to both sides)
2x = - 14
Division Property of Equality (Divide both sides by 2)
x = -7

Answer:
Test statistic = 2.8965
Step-by-step explanation:
The test statistic is given by the formula
z = (x - μ)/σₓ
μ = mean = 0.799
x = proportion of literate people in Tamil Nadu = (983/1185) = 0.8295
σₓ = standard error of this calculated proportion = √[p(1-p)/n]
= √(0.8295 × 0.1705/1185) = 0.01093
z = (x - μ)/σₓ
z = (0.8295 - 0.799)/0.01093 = 2.8965
z = 2.8965
