Question

7x - 5[x - {7 - 6x + 18}]=3x + 1

Answer 1

Hey friend,
Here is the answer you were looking for:
$7x - 5(x - (7 - 6x + 18)) = 3x + 1 \\ \\ 7x - 5(x - (15 - 6x) )= 3x + 1 \\ \\ 7x - 5(x - 15 - 6x) = 3x + 1 \\ \\ 7x - 5( - 15 - 5x) = 3x + 1 \\ \\ 7x - 5 \times - 15 - 5 \times - 5x = 3x + 1 \\ \\ 7x + 75 + 25x = 3x + 1 \\ \\ 32x + 75 = 3x + 1 \\ \\ 32x - 3x = 1 - 75 \\ \\ 29x = - 74 \\ \\ x = \frac{ - 74}{29}$


Hope this helps!!
