20jx+550j=1050
Whakamahia te āhuatanga tohatoha hei whakarea te 10j ki te 2x+55.
\left(20x+550\right)j=1050
Pahekotia ngā kīanga tau katoa e whai ana i te j.
\frac{\left(20x+550\right)j}{20x+550}=\frac{1050}{20x+550}
Whakawehea ngā taha e rua ki te 20x+550.
j=\frac{1050}{20x+550}
Mā te whakawehe ki te 20x+550 ka wetekia te whakareanga ki te 20x+550.
j=\frac{105}{2x+55}
Whakawehe 1050 ki te 20x+550.
20xj+550j=1050
Whakamahia te āhuatanga tohatoha hei whakarea te 10j ki te 2x+55.
20xj=1050-550j
Tangohia te 550j mai i ngā taha e rua.
20jx=1050-550j
He hanga arowhānui tō te whārite.
\frac{20jx}{20j}=\frac{1050-550j}{20j}
Whakawehea ngā taha e rua ki te 20j.
x=\frac{1050-550j}{20j}
Mā te whakawehe ki te 20j ka wetekia te whakareanga ki te 20j.
x=-\frac{55}{2}+\frac{105}{2j}
Whakawehe 1050-550j ki te 20j.
