Question

What is the value of x in this equation? 4x + 2 – 23(92 + 92x) = 7

Answer 1

Answer:

-707/704

Step-by-step explanation:

4x + 2 - 2116 - 2116x = 7

-2112x = 2121

x = 2121/-2112 = -707/704

Answer 2

Answer:

 x= 2121/-2112 = -707/704 = -1.00426136

Step-by-step explanation:

4x + 2 – 23(92 + 92x) = 7

1. Eliminate the 2 by substracting both side by -2

               4x - 23(92+92x) = 5

    2. Discriminate by multiplying -23 with 92 and -23 with 92x

               4x - 2116 -2116x = 5

    3. Add 2116 both sides to eliminate -2116

              4x -2116x = 2121

    4. combine 4x-2116x together

             -2112x = 2121

    5. Divide both sides with -2112

              x= 2121/-2112 = -707/704 = -1.00426136
