a) \(4590:\left(x-24+14\right)=30\)
\(x-24+14=4590:30\)
\(x-24+14=153\)
\(x-24=153-14\)
\(x-24=139\)
\(x=139+24\)
\(x=163\)
b) \(61\times\left(126:x\right)=1281\)
\(126:x=1281:61\)
\(126:x=21\)
\(x=126:21\)
\(x=6\)
b. 61 × ( 126 : x ) = 1281
x = 126 : x = 1281 ÷ 61 = 21
x = 126÷21
x = 6
a) 4590 ÷ ( x− 24 + 14 ) = 30
4590 ( x- 10 ) = 30
x - 10 = 4590 : 30
x-10 = 153
x = 153+10
x = 163
