`@` `\text {Ans}`

`\downarrow`

`1,`

`a)`

`x + 12 = 25`

`\Rightarrow x = 25 - 12`

`\Rightarrow x = 13`

Vậy, `x = 13`

`b)`

`134 - x = 125 \div 5`

`\Rightarrow 134 - x = 25`

`\Rightarrow x = 134 - 25`

`\Rightarrow x=109`

Vậy, `x = 109`

`c)`

`2 \times x - 53 = 22`

`\Rightarrow 2x = 22 + 53`

`\Rightarrow 2x = 75`

`\Rightarrow x = 75 \div 2`

`\Rightarrow x =37,5`

Vậy, `x = 37,5`

`d)`

`7 + 3 \times x = 16`

`\Rightarrow 3x = 16 - 7`

`\Rightarrow 3x =9`

`\Rightarrow x = 9 \div 3`

`\Rightarrow x = 2`

Vậy, `x = 2.`

Answer 2

`2,`

`a)`

`(x + 3) - 15 = 2`

`\Rightarrow x + 3 = 2 + 15`

`\Rightarrow x +3 = 17`

`\Rightarrow x = 17 - 3`

`\Rightarrow x = 14`

Vậy, `x = 14`

`b)`

`33 + (x - 1) = 56`

`\Rightarrow x - 1 = 56 - 33`

`\Rightarrow x - 1 = 23`

`\Rightarrow x = 23 + 1`

`\Rightarrow x = 24`

Vậy, `x = 24`

`c)`

`5 \times (4 + 6 \times x) = 290`

`\Rightarrow 4 + 6x = 290 \div 5`

`\Rightarrow 4 + 6x = 58`

`\Rightarrow 6x = 58 - 4`

`\Rightarrow 6x = 54`

`\Rightarrow x = 54 \div 6`

`\Rightarrow x = 9`

Vậy, `x = 9`

`d)`

`x. 3,7 + x. 6,3 = 120`

`\Rightarrow x . (3,7 + 6,3) = 120`

`\Rightarrow x . 10 = 120`

`\Rightarrow x = 120 \div 10`

`\Rightarrow x = 12`

Vậy,` x = 12.`
