a) \(\frac{3}{4}+x=-\frac{1}{2}\)
\(x=-\frac{1}{2}-\frac{3}{4}\)
\(x=-\frac{5}{4}\)
b) \(\frac{2}{3}+x=1\)
\(x=1-\frac{2}{3}\)
\(x=\frac{1}{3}\)
Chúc bn hok tốt
\(a,\frac{3}{4}+x=-\frac{1}{2}\)
=> \(x=-\frac{1}{2}-\frac{3}{4}=-\frac{5}{4}\)
\(b,\frac{2}{3}+x=1\)
=> \(x=1-\frac{2}{3}=\frac{1}{3}\)
Chúc bạn Hk tốt!!!!

a) 3/4 + x = -1/2
x = -1/2 - 3/4
x = 5/4
b) 2/3 + x = 1
x = 1 - 2/3
x = 1/3
