Question

1/2 (6-5 1/2x) = 2 1/4x-3 1/2

Answer 1

$\displaystyle \frac{1}{2}(6-5\frac{1}{2}x)=2\frac{1}{4}x-3\frac{1}{2}\\\\6-5\frac{1}{2}x=2*2\frac{1}{4}x-2*3\frac{1}{2}\\ \\6-\frac{11}{2}x=2*\frac{9}{4}x-2*\frac{7}{2}\\ \\6-\frac{11}{2}x=\frac{9}{2}x-7\\ \\12-11x=9x-14\\ -11x-9x=-14-12\\ -20x=-26\\ \\x=\frac{13}{10}=1\frac{3}{10}=1,3$
