=x+13=-8
x=-8-13
x=-21
\(x-\left(12-25\right)=-8\)
\(=>x-12+25=-8\)
\(=>x+13=-8\)
\(=>x=-8-13=-21\)
\(x-\left(12-25\right)=-8\)
\(x-\left(12-25\right)=x+13\)
\(x+13=-2^3\)
\(x+13=-8\)
\(x=\left(-8\right)-13\)
\(x=-21\)
x - ( 12 - 25 ) = -8
<=>x-12+25=-8
<=>x+13=-8
<=>x=-21
Vậy x=-21
\(x-\left(12-25\right)=-8\)
\(\Leftrightarrow x-12+25=-8\)
\(\Leftrightarrow x-13=-8\)
\(\Leftrightarrow x=-8-13\)
\(\Leftrightarrow x=-21\)
x-(12-25)=-8
<=> x+13=8
<=> x=-5
Vậy x=-5
