Solve the equation for d: 0.2 (d-6) = 0.3d + 5 - 3 + 0.1d

Sagot :

0.2(d-6)=0.3d + 5-3+0.1d 0.2d - 1.2 = 0.4d + 2 0.4d-0.2d= -1.2-2 0.2d=-3.2 D= -3.2/0.2 D= -16 Check 0.2(-16-6)=0.3(-16)+5-3+(0.1•-16) -4.4=-4.4

[tex]0.2 (d-6) = 0.3d + 5 - 3 + 0.1d\\ \\0.2d-1.2 = 0.4d +2 \\ \\0.2d-0.4 = 2 + 1.2\\\\-0.2d=3.2\ \ / \cdot (-10)\\\\2d=-32\ \ /:2\\\\d=-16[/tex]
