Whakaoti i te 3(x+14)+4(x+14)=35

$$3 ( x + 14 ) + 4 ( x + 14 ) = 35$$

Whakaoti mō x

$$x=-9$$

Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+14.

$$3x+42+4\left(x+14\right)=35$$

Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te x+14.

$$3x+42+4x+56=35$$

Pahekotia te 3x me 4x, ka 7x.

$$7x+42+56=35$$

Tāpirihia te 42 ki te 56, ka 98.

$$7x+98=35$$

Tangohia te 98 mai i ngā taha e rua.

$$7x=35-98$$

Tangohia te 98 i te 35, ka -63.

$$7x=-63$$

Whakawehea ngā taha e rua ki te 7.

$$x=\frac{-63}{7}$$

Whakawehea te -63 ki te 7, kia riro ko -9.

$$x=-9$$
