Simplify expression using distributive property: Simplify 2(5−d) by using the distributive property.2(5−d)=2(5)+2(−d)=10−2d
Set expression equal to other side of equation: Set the simplified expression equal to the other side of the equation. 10−2d=2−4d
Add 2d to both sides: Add 2d to both sides to get all the d terms on one side.10−2d+2d=2−4d+2d10=2−2d
Isolate the term: Add to both sides to isolate the d term.\newline101010 + 222d = 222 - 222d + 222d\newline101010 + 222d = 222
Subtract 222 from both sides: Subtract 222 from both sides to solve for ddd.10+2d−2=2−210 + 2d - 2 = 2 - 210+2d−2=2−28+2d=08 + 2d = 08+2d=0
Divide both sides by 222: Divide both sides by 222 to find the value of ddd. 8+2d2=02\frac{8 + 2d}{2} = \frac{0}{2}28+2d=20 4+d=04 + d = 04+d=0
Subtract 444 from both sides: Subtract 444 from both sides to get the final value of d.\newline4+d−4=0−44 + d - 4 = 0 - 44+d−4=0−4\newlined=−4d = -4d=−4
