Question

8:x=-2


X:2=-4


-3x=12


(100-x)(99-x)(98-x)=0


2 la puterea 21 X +2 l puterea 22 = 2 la puterea 23



40 x=80

Answer 1

8÷x = -2
x = -4

x : 2 = -4
x = -8

-3x = 12
x = -4

(100 - x)(99-x)(98-x)=0
x = 100, 99 sau 98

${2}^{21} x + {2}^{22} = {2}^{23} \\ x = ( {2}^{23} - {2}^{22} ) \div {2}^{21} = {2}^{22}(2 - 1) \div {2}^{21} = {2}^{22} \div {2}^{21} = 2$

40x = 80
x = 2
