Answer 1

-9x-50/10

Explanation:

Answer 2

`\boldsymbol{\sf{\left(-(3)/(5)x-7\right)-\left(-12+(3)/(10)x\right)}}`

Remove unnecessary parentheses.

`\boldsymbol{\sf{-(3)/(5)x-7-\left(-12+(3)/(10)x\right)}}`

Calculate the multiplication expression.

`\boldsymbol{\sf{-(3x)/(5)-7-\left(-12+(3)/(10)x\right) }}`

We solve the equation in fraction form.

`\boldsymbol{\sf{-(3x)/(5)-7-(3x-120)/(10)=\boxed{\boldsymbol{\sf{-(9x-50)/(20) }}} }}\bf{\iff}\boxed{\boxed{\bf{Answer }}}`
