Exercise 62 Page 86

How can you isolate d on one side of the equation?

d=-18

Practice makes perfect

To solve the equation, we have to isolate d on one side. By multiplying both sides of the equation by 92, we can eliminate 29 and isolate the variable.

-4=2/9d
MultEqn

LHS * 9/2=RHS* 9/2

-4* 9/2=2/9d* 9/2

RearrangeEqn

Rearrange equation

d=-18

Therefore, d=-18 is the solution to the equation. To check that we have the correct solution, we can substitute d=-18 into the original equation and simplify.

-4=2/9d
Substitute

d= -18

-4? =2/9*( -18)
MoveRightFacToNum

a/c* b = a* b/c

-4? =2* (-18)/9
MultNegPos

(- a)b = - ab

-4? =-36/9
CalcQuot

Calculate quotient

-4=-4

Since the left-hand side and right-hand side are equal, we have the correct solution.
