1)3.8.2-5.8
=8(6-5)=8
2)4.25-32:8
=4(25-1)=4.24=96
3)3.25-16:4
=75-4=71
4)4.25-3.8
=4(25-6)
=4.19=76
\(\left(2x-2\right).2024=0\)
\(\left(2x-2\right)=0\div2024\)
\(2x-2=0\)
\(2x=0+2\)
\(2x=2\)
\(x=1\)
\(15\div\left(6-x\right)=5\)
\(\left(6-x\right)=15\div5\)
\(6-x=3\)
\(x=6-3\)
\(x=3\)
\(\left[\left(10-x\right).2+5\right]\div3-2=3\)
\(\left[\left(10-x\right).2+5\right]\div3=3+2\)
\(\left[\left(10-x\right).2+5\right]\div3=5\)
\(\left(10-x\right).2+5=5.3\)
\(\left(10-x\right).2+5=15\)
\(\left(10-x\right).2=15-5\)
\(\left(10-x\right).2=10\)
\(\left(10-x\right)=10\div2\)
\(10-x=5\)
\(x=10-5\)
\(x=5\)
\(134\div\left(x-3\right)=35+160\div5\)
\(134\div\left(x-3\right)=35+32\)
\(134\div\left(x-3\right)=67\)
\(\left(x-3\right)=134\div67\)
\(x-3=2\)
\(x=2+3\)
\(x=5\)
d) ( x : 3 - 4 ) . 5 = 15
=> x : 3 - 4 = 15 : 5 = 3
=> x : 3 = 3 + 4 = 7
=> x = 7 . 3 = 21
