3/5 (10x + 15) = +30 help me please

Mathematics
1 answer:
sergeinik [125]3 years ago
7 0

Answer:

x = 3.5

Step-by-step explanation:

\frac{3}{5} (10x + 15) = 30

10x + 15  = 30 * \frac{5}{3}  

10x + 15   = 10 * 5

10x + 15   = 50           {Subtract 15 form both sides}

         10x = 50 -15

        10x = 35         {Divide both sides bt 10}

    10x/10 = 35/10  

          x = 3.5
