((4-x)/5)+((x+2)/3)=6 Please Help Soon

Vlada [557]

Answer: x = 34

Step-by-step explanation:

⁴ ⁻ˣ/₅ + ˣ + 2/₃ = 6

Now resolve into fraction and convert to a linear equation

4 - x /₅ + x + 2/₃ = 6

3( 4 -x ) + 5( x + 2 )/15 = 6

3( 4 - x ) + 5( x + 2 ) = 6 x 15

12 - 3x + 5x + 10 = 90

2x + 22 = 90

2x = 90 - 22

2x = 68

x = 34
