a) 7 + x = 362 => x = 362 - 7 => x = 355
Vậy x = 355
b) 25 - x = 15 => x = 25 – 15 => x = 10
Vậy x = 10
c) x - 56 = 4 => x = 56 + 4 => x = 60.
Vậy x = 60
` a. 7 + x = 362 `
` x = 362 - 7 `
` x = 355.`
Vậy ` x= 355`
`b. 25 - x = 15 `
` x = 25 - 15 `
` x = 10 `
Vậy ` x = 10`
`c. x - 56 = 4`
` x = 4 + 56 `
` x = 60`
Vậy ` x = 60.`
a)
\(7+x=362\)
\(x=362-7\)
\(x=355\)
b)
\(25-x=15\)
\(x=25-15\)
\(x=10\)
c)
\(x-56=4\)
\(x=4+56\)
\(x=60\)
