Question

solve for x 1) 3/4(7x-1) - (2x+x-1/2=2x+3/2​

Answer 1

$3/4(7x - 1) - [2x - (1 - x)/2] = (x + 4)/2 \\ (21x - 3)/4 - [4x/2 - (1 - x)/2] = (x + 4)/2 \\ (21x - 3)/4 - (5x - 1)/2 = (x + 4)/2 \\ (21x - 3)/4 - (10x - 2)/4 = (2x + 8)/4 \\ 21x - 3 - 10x + 2 = 2x + 8 \\ 11x - 1 = 2x + 8 \\ 9x = 9 \\ x=1$
