Question

x+2=5

2x-30=-14

14.23-4.23-4(x+5)=30

3^x:3⁵=45:5

Answer 1

x+2 = 5

x = 5-2

x = 3

2x - 30 = -14

2x = -14 +30

2x = 16

x= 16:2

x=8

14x23-4x23-4(x+5) = 30

322 - 92- 4(x+5) = 30

230 - 4(x+5) = 30

4(x+5)  = 230 - 30

4(x+5)  = 200

x+5 = 200 :4

x+5 = 50

x = 50 - 5

x = 45

3^x :3⁵ = 45:5

3^x :3⁵ = 9 = 3²

3^x :3⁵ =3²

=> 3^x = 3² x 3⁵

=>3^x = 3⁷

=> x = 7 

Answer 2

x+2=5

=> x=5-2

=> x=3.

2x-30=-14

=> 2x=-14+30

=> 2x=16

=> x=16:2

=> x=8.

14.23-4.23-4.(x+5)=30

=> 23.(14-4)-4.(x+5)=30

=> 23.10-4.(x+5)=30

=> 230-4.(x+5)=30

=> 4.(x+5)=230-30

=> 4.(x+5)=200

=> x+5=200:4

=> x+5=50

=> x=50-5

=> x=45.

3^x:3⁵=45:5

=> 3^x-5=9

=> 3^x-5=3²

=> x-5=2

=> x=2+5

=> x=7.

Answer 3

x=3

x=8

x=45

x=3
