Let's begin by solving the
equation
for y.
3x-5y=9
SubEqn
LHS-3x=RHS-3x
3x-3x-5y=9-3x
SubTerms
Subtract terms
- 5y=9-3x
DivEqn
.LHS /-5.=.RHS /-5.
-5y/-5=9-3x/-5
ReduceFrac
a/b=.a /-5./.b /-5.
y=9-3x/-5
DivNegNeg
- a/- b=a/b
y=-(9-3x)/5
DistrNegSignSwap
-(b-a)=a-b
y=3x-9/5
To find the value of y for each of the x-values, we substitute them into the equation and evaluate.
x
3x-9/5
