Question

\(a.6x+x=5^{11}:5^9+3^1\)

\(b.5x+3x=3^6:3^3.4+12\)

 

Answer 1

a) 6x + x = 5¹¹ : 5⁹ + 3¹

7x = 5² + 3

7x = 25 + 3

7x = 28

x = 28 : 7

x = 4

b) 5x + 3x = 3⁶ : 3³ . 4 + 12

8x = 3³ . 4 + 12

8x = 27 . 4 + 12

8x = 108 + 12

8x = 120

x = 120 : 8

x = 15

Answer 2

a) \(6x+x=5^{11}:5^9+3^1\)

             \(7x=25+3\)

              \(7x=28\)

                 \(x=4\)

b) \(5x+3x=3^6:3^3.4+12\)

              \(8x=27.4+12\)

              \(8x=108+12\)

              \(8x=120\)

                 \(x=15\)
