1.	Solve the equation and also check your results:0.18(5x – 4) = 0.5x + 0.8
Answer» 0.18(5x – 4) = 0.5x + 0.8 Let us rearrange the equation 0.18(5x – 4) – 0.5x = 0.8 0.90x – 0.72 – 0.5x = 0.8 0.90x – 0.5x = 0.8 + 0.72 0.40x = 1.52 x = 1.52/0.40 = 3.8 Let us verify the given equation now, 0.18(5x – 4) = 0.5x + 0.8 By substituting the value of ‘x’ we get, 0.18(5(3.8)-4) = 0.5(3.8) + 0.8 0.18(19-4) = 1.9 + 0.8 2.7 = 2.7 Hence, the given equation is verified.

Answer»

0.18(5x – 4) = 0.5x + 0.8

Let us rearrange the equation

0.18(5x – 4) – 0.5x = 0.8

0.90x – 0.72 – 0.5x = 0.8

0.90x – 0.5x = 0.8 + 0.72

0.40x = 1.52

x = 1.52/0.40

= 3.8

Let us verify the given equation now,

0.18(5x – 4) = 0.5x + 0.8

By substituting the value of ‘x’ we get,

0.18(5(3.8)-4) = 0.5(3.8) + 0.8

0.18(19-4) = 1.9 + 0.8

2.7 = 2.7

Hence, the given equation is verified.
