Question

274 X x 265 X x = 5130

TÌM x 

Answer 1

$274\times x-265\times x=5130$

$\Rightarrow x\times \left(274-265\right)=5130$

$\Rightarrow x\times 9=5130$

$\Rightarrow x=570$

Answer 2

Ta có: \(274\times x+265\times x=5130\)

=>\(x\times\left(274+265\right)=5130\)

=>\(x\times539=5130\)

=>\(x=\dfrac{5130}{539}\)
