Question

решите уравнение. 34+2×(2x-9)=48

45-2×(3x-8)=25​

Answer 1

$34 + 2(2x - 9) = 48 \\ 4x - 18 = 14 \\ 4x = 32 \\ x = 8$

$45 - 2(3x - 8) = 25 \\ - 6x + 16 = - 20 \\ - 6x = - 36 \\ x = 6$

Answer 2

34+2×(2x-9)=48

34+4х-18-48=0

4х-32=0

4х=32

х=3324

х=8

Ответ: х=8

45-2×(3x-8)=25​

45-6х+16-25=0

36-6х=0

-6х= -36

х= -36/(-6)

х= 6

Ответ: х=6
