Answer:x = 7.8
Solution:
7(x + 5) - 3(2x + 3) = 33.8
Distribute them
7x + 35 - 6x - 9 = 33.8
Combine the like terms and then compute them
x + 26 = 33.8
Transpose 26 and the change the sign
x = 33.8 - 26
Solve
x = 7.8
Checking:
7(x + 5) - 3(2x + 3) = 33.8
7(7.8 + 5) - 3[2(7.8) + 3] = 33. 8
7(12.8) - 3(18.7) = 33.8
89.6 - 55. 8 = 33.8
33.8 = 33.8 TRUE
