\(x:7+15=-17\)
\(\Leftrightarrow\dfrac{1}{7}x=-32\)
\(\Leftrightarrow x=-224\)
`x : 7 + 15 = -17`
`x : 7 = -15 - 17`
`x : 7 = -32`
`x=-32.7`
`x=-224`
Vậy `x=-224`
\(x:7+15=-17\)
\(x:7=-17-15\)
\(x:7=-32\)
\(x=-32.7\)
\(x=-224\)
Vậy \(x=-224\)
`x : 7 + 15 = -17`
`=> x : 7 = -17 - 15`
`=> x : 7 = -32`
`=> x = -32 xx 7`
`=> x = -224`
Vậy `x=-224`
x:7+15=−17
x:7=−15−17
x:7=−32
x=−32.7
x=−224
Vậy x=−224
\(x:7+15=-17\)
\(x:7\) \(=\left(-17\right)-15=-32\)
\(x\) \(=\left(-32\right).7=-224\)
