Question

Qual o conjunto solução da equação: 5(2x - 1 ) = 3(x + 10)

S= {7}

S = {5}

S = {35}

S = {30}

S = {40}

Answer 1

$\mathsf{5(2x-1)=3(x+10)}\\\mathsf{10x-5=3x+30}\\\mathsf{10x-3x=30+5}\\\mathsf{7x=35}\\\mathsf{x=\dfrac{35}{7}}$

$\mathsf{x=5}$

$\boxed{\boxed{\boxed{\mathsf{s=\{5\} }}}}$
