Answer:
x = 1/7
Step-by-step explanation:
You want to know the solution to (2/7)(14x -7) +3 = (1/4)(2x +6).
Multiplying by 28 will clear the fractions.
8(14x -7) +3(28) = 7(2x +6)
112x -56 +84 = 14x +42 . . . . . . . eliminate parentheses
98x = 14 . . . . . . . . . . . . . . . add -28-14x
x = 1/7 . . . . . . . . . . . . . . divide by 98
