Linear Equation
5 raruraru e ōrite ana ki:
\frac { - 10 + 1.6 y } { 3 } + \frac { y } { 5 } = 4
Tohaina
Kua tāruatia ki te papatopenga
5\left(-10+1.6y\right)+3y=60
Me whakarea ngā taha e rua o te whārite ki te 15, arā, te tauraro pātahi he tino iti rawa te kitea o 3,5.
-50+8y+3y=60
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te -10+1.6y.
-50+11y=60
Pahekotia te 8y me 3y, ka 11y.
11y=60+50
Me tāpiri te 50 ki ngā taha e rua.
11y=110
Tāpirihia te 60 ki te 50, ka 110.
y=\frac{110}{11}
Whakawehea ngā taha e rua ki te 11.
y=10
Whakawehea te 110 ki te 11, kia riro ko 10.
