7-4x < 5. 3
I 7-4x I <- 5 3 I
(d) 1 — 2 x = 0 => x = 0.5
Here are the solutions to the given linear inequalities:
(a) 2x+3 < 4-5x => 7x < 1 => x < 0.1428
(b) 1-2x < 5 => -x < 4 => x > -4
(c) 5 3 < 6 => 5/3 < 6 => 1.666 < 6 This is not possible.
(d) 7-4x < 3 => -x < -4 => x > 4
I hope this helps! Let me know if you have any other questions.
re are the solutions to the given linear equations:
(a) 5 x + 3 (2 y — 4) = 0 => 5 x + 6 y - 12 = 0 => 6 y = 5 x + 12 => y = (5/6) x + 2
(b) 5 x + 3 (2 y — 4) = 7 => 5 x + 6 y - 12 = 7 => 6 y = 5 x + 19 => y = (5/6) x + 3.1666
(c) 2 — 2 (x + 4 y) = 0 => -2 x - 8 y = 0 => x = -4 y
