a) \(\Rightarrow x=102:2=51\)
b) \(\Rightarrow x=301-19=282\)
c) \(\Rightarrow x=93-27=66\)
\(a,\Rightarrow x=51\\ b,\Rightarrow x=282\\ c,\Rightarrow x=66\)
a) 2x = 102
x = 102 : 2
x = 51
b) x + 19 = 301
x = 301 - 19
x = 282
c) 93 – x = 27
x = 93 - 27
x = 66
\(a)x=102:2=51\)
\(b)x+19=301\)
\(x=301-19\)
\(x=282\)
\(c)93-x=27\)
\(x=93-27\)
\(x=66\)
