Question

Упростите выражение и решите 3/4 (х-6)+2 где х = 8

Answer 1

3/4х-4,5+2=3/4х-2,5=6-2,5=3,5

Answer 2

$\frac{3}{4} \times (x - 6) + 2 = \\ \frac{3}{4} x - \frac{3}{4} \times 6 + 2 = \\ \frac{3}{4} x - 4.5 + 2 = \\ \frac{3}{4} x - 2.5 = \\ \frac{3}{4} \times 8 - 2.5 = \\6 - 2.5 = \\3.5 \: .$
