`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`

a)

�−452×2=180x−452×2=180

�−904=180x−904=180

�=180+904x=180+904

�=1084x=1084

�)b)

�+58÷2=60x+58÷2=60

�+29=60x+29=60
