135-5(x+4)=35 25+3(x-8)=106 3^2(x+4)-5*2^2

${135-5(x+4)=35}$

${5(x+4)=135-35}$

${5(x+4)=100}$

${x+4 = 100 : 5}$

${x+4 = 20 }$

    ${ x = 20 – 4}$

    ${x= 16 }$

Vậy ${ x=16}$

${25+3(x-8)=106}$

${3(x-8) = 106 – 25}$

${3(x-8) = 81}$

${x-8=81: 3}$

${x- 8 = 27}$

${x=27+8}$

${x=35}$

Vậy ${x=35}$

${ 3^{2} ( x+4) – 5.2^{2} }$ = ${?}$
