Exercise 7 Page 306

Practice makes perfect
a We can solve the equation for x by performing inverse operations on both sides until x is isolated.
3x-2y=18
AddEqn

LHS+2y=RHS+2y

3x=18+2y
DivEqn

.LHS /3.=.RHS /3.

x=18+2y/3
WriteSumFrac

Write as a sum of fractions

x=18/3+2y/3
CalcQuot

Calculate quotient

x=6+2y/3
b We can solve the equation for y by performing inverse operations on both sides until y is isolated.
3x-2y=18
AddEqn

LHS+2y=RHS+2y

3x=18+2y
SubEqn

LHS-18=RHS-18

3x-18=2y
DivEqn

.LHS /2.=.RHS /2.

3x-18/2=y
WriteDiffFrac

Write as a difference of fractions

3x/2-18/2=y
CalcQuot

Calculate quotient

3x/2-9=y
RearrangeEqn

Rearrange equation

y=3x/2-9
c We can solve the equation for r by performing inverse operations on both sides until r is isolated.
C=2Ď€ r
DivEqn

.LHS /2Ď€.=.RHS /2Ď€.

C/2Ď€=r
RearrangeEqn

Rearrange equation

r=C/2Ď€
