`@` `\text {Ans}`

`\downarrow`

`a)`

`x - 452 \times 2 = 180`

`x - 904 = 180`

`x = 180 + 904`

`x = 1084`

`b)`

`x + 58 \div 2 = 60`

`x + 29 = 60`

`x = 60 - 29`

`x = 31`

`c)`

`x - 1 - 2 - 3 - 4 = 0`

`x - (1 + 2 + 3 + 4) = 0`

`x - 10 = 0`

`x = 0 + 10`

`x = 10`

Answer 2

[Phạm Vũ Phương Thảo]

$a)$

$x-452\times 2=180$

$x-904=180$

$x=180+904$

$x=1084$

$b)$

$x+58÷2=60$

$x+29=60$

$x=60-29$

$x=31$

$c)$

$x-1-2-3-4=0$

$x-(1+2+3+4)=0$

$x-10=0$

$x=0+10$

$x=10$
