Question

-(41-9)+(x-21)=-1

Answer 1

−(32)+(𝑥−21)=−1

−32+𝑥−21=−1

−53+𝑥=−1

𝑥−53=−1

𝑥−53+53=−1+53

𝑥=52

Answer 2

\(-\left(41-9\right)+\left(x-21\right)=-1\)

⇔\(-32+x-21+1=0\)

⇔\(x-52=0\)

⇔\(x=52\)

Answer 3

\(\text{-(41-9)+(x-21)=-1}\\ -41+9+x-21=-1\\ -32+x-21=-1\\ -32+x=-1+21\\ -32+x=20\\ x=20-\left(-32\right)\\ x=52\)
