8(х-14)=562)(46-х)•19=4183)9(143-13х)=2344)17(5х-16)=238помогите решить

Приветствую Вас!

1)
8(x+14)=56
$\frac{8(x-14)}{8} = \frac{56}{8}$
$x-14= \frac{56}{8}$
$x-14=7$
$x=7+14$
$x=21$

2)
(46-x)*19=418
$\frac{19(46-x)}{19} = \frac{418}{19}$
$46-x= \frac{418}{19}$
$46-x=22$
$-x=-24$
$x=24$

3)
9(143-13х)=234
$\frac{9(143-13x)}{9} = \frac{234}{9}$
$113-13x= \frac{234}{9}$
$143-13x=26$
$-13x=-117$
$x=9$

4)
17(5х-16)=238
$\frac{17(5x-16)}{17} = \frac{238}{17}$
$5x-16= \frac{238}{17}$
$5x-16=14$
$5x=30$
$x=6$
