Question

5√2(x-√8)-2(x-5)= x(3√2-2)

Answer 1

5√2(x-√8)-2(x-5)= x(3√2-2)
5x√2-5√2√8-(2x-10)=3x√2-2x
5x√2-5√16-2x+10=3x√2-2x

5x√2-5√16+10=3x√2
5x√2-5×4+10=3x√2
5x√2-10=3x√2
5x√2=3x√2+10
2x√2=10
x√2=5
x=5/√2
x=5√2/2

Answer 2

5√2(x-√8)-2(x-5)=x(3√2-2)⇒
5√2x-5√16-2x+10=3√2x-2x⇒
5√2x-20+10-3√2x+2x-2x=0⇒
2√2x-10=0⇒
2√2x=10⇒x=10/2√2⇒
x=5√2
