a: x=-1/3-1/4=-7/12
b: x=5/8+3/7=35/56+24/56=59/56
c: x=0,472-1,634=-1,162
d: =>x+2,12=-1,75
hay x=-3,87
a) \(\dfrac{1}{4}+x=-\dfrac{1}{3}\)
\(x=-\dfrac{1}{3}-\dfrac{1}{4}\)
\(x=-\dfrac{7}{12}\)
b) \(-\dfrac{3}{7}+x=\dfrac{5}{8}\)
\(x=\dfrac{5}{8}+\dfrac{3}{7}\)
\(x=\dfrac{59}{56}\)
c) \(0,472-x=1,634\)
\(x=0,472-1,634\)
\(x=-1,162\)
d) \(-2,12-x=1\dfrac{3}{4}\)
\(x=-2,12-\dfrac{7}{4}\)
\(x=-3,87\)
