a: (x-35)-120=0

=>x-35=120

=>x=120+35=155

b: 59(x-29)=0

=>x-29=0

=>x=29

c: 2x+3x=45:3

`@` `\text {Ans}`

`\downarrow`

`(x - 35) - 120 = 0`

`x - 35 = 0 + 120`

`x - 35 = 120`

`x = 120+ 35`

`x = 155`

Vậy, `x = 155`

____

`(x - 29)*59 = 0`

`x - 29 = 0 \div 59`

`x - 29 = 0`

`x = 0 + 29`

`x = 29`

Vậy, `x= 29`

____

`2x + 3x = 45 \div 3`

`(2 + 3)x = 15`

`5x = 15`

`x = 15 \div 5`

`x = 3`

Vậy, `x = 3.`
