Answer:
Step-by-step explanation:
Given : (3/2)(5x - 3) + 10 = 18x - 2 , (10x + 16)/5 + (22 - 3x)/10 = π/2 ,
0.15x + 0.01(0.1x - 10) = 100/120
To find : Solve for x
Solution:
(3/2)(5x - 3) + 10 = 18x - 2
multiplying both sides by 2
=> 3(5x - 3) + 20 = 36x - 4
=> 15x - 9 + 20 = 36x - 4
=> 21x = 15
=> x = 15/21
=> x = 5/7
(10x + 16)/5 + (22 - 3x)/10 = π/2
multiplying by 10 on both sides
=> 2(10x + 16) + 22 - 3x = 5π
=> 20x + 32 + 22 - 3x = 5π
=> 17x = 5π - 54
=> x = (5π - 54)/17
0.15x + 0.01(0.1x - 10) = 100/120
=> 1.8x + 1.2(0.1x - 10) = 100
=> 1.8x + 0.12x - 12 = 100
=> 1.92x = 88
=> x = 88/1.92
=> x = 45.83
