5.x-(-3) = 13
5.x+3 = 13
5.x = 13-3
5.x = 10
x = `10:5
x = 2
Vậy : x = 2
5x - (-3) = 13
5x + 3 = 13
5x = 13 - 3
5x = 10
x = 10 : 5
x = 2
Vậy x = 2
5.x-(-3)= 13
=>5.x+3= 13
=> 5.x = 13-3
=> 5.x = 10
=> x = 10 : 5
=> x = 2
Vay x = 2
\(5x-\left(-3\right)=13\)
\(5x+3=13\)
\(5x=10\)
\(x=2\)
5.x-(-3)=13
5.x+3=13
5x=13-3
5x=10
x=10:5
x=2
