Question

calcule ME AJUDAAAAA​

Answer 1

3x+2=11

3x=11-2

3x=9

x=9/3=3

7x-2=12

7x=12+2

7x=14

x=14/7=2

5x-8=12

5x=12+8

5x=20

x=20/5=4

2x-18=0

2x=18

x=18/2=9

2x+4=8

2x=8-4

2x=4

x=4/2=2

{-4+[2+(5)*(2)]-√121}

{-4+[2+10]-11}

{-4+12-11}

3

{25+[12+(50)*(5)]+√81}

{25+[12+250]+9}

{25+262+9}

296

{-√9+[(12)/(2)+3]-2}

{-3+[6+3]-2}

{-3+9-2}

4

{15+[2+(-3)*(2)]+√49}

{15+[2-6]+7}

{15-4+7}

18
