Решите уравнение: 1) 3x = 36-x; 2) 13x + 24 = 9x; 3) 8x + 5 = 5x + 29; 4) 7x − 4 = 4x + 17; 5) x + 2 = 5x + 18; 6) 7- 4x = 2x - 23.

Решим уравнения по порядку: 1) 3x = 36 - x $$3x = 36 - x$$ $$3x + x = 36$$ $$4x = 36$$ $$x = rac{36}{4}$$ $$x = 9$$ Ответ: 9 2) 13x + 24 = 9x $$13x + 24 = 9x$$ $$13x - 9x = -24$$ $$4x = -24$$ $$x = rac{-24}{4}$$ $$x = -6$$ Ответ: -6 3) 8x + 5 = 5x + 29 $$8x + 5 = 5x + 29$$ $$8x - 5x = 29 - 5$$ $$3x = 24$$ $$x = rac{24}{3}$$ $$x = 8$$ Ответ: 8 4) 7x - 4 = 4x + 17 $$7x - 4 = 4x + 17$$ $$7x - 4x = 17 + 4$$ $$3x = 21$$ $$x = rac{21}{3}$$ $$x = 7$$ Ответ: 7 5) x + 2 = 5x + 18 $$x + 2 = 5x + 18$$ $$x - 5x = 18 - 2$$ $$-4x = 16$$ $$x = rac{16}{-4}$$ $$x = -4$$ Ответ: -4 6) 7 - 4x = 2x - 23 $$7 - 4x = 2x - 23$$ $$-4x - 2x = -23 - 7$$ $$-6x = -30$$ $$x = rac{-30}{-6}$$ $$x = 5$$ Ответ: 5
