Question

Решите уравнения:
4*(х-2)-12=36-4х
9х-17/2 -5х-4=1

Answer 1

4x - 8 - 12 = 36 - 4x
8x = 56
x = 56/8
x = 7

9x - 8.5 - 5x - 4 = 1
4x - 12.5 = 1
4x = 13.5
x = 13.5/4
x = 3.375

Answer 2

4*(х-2)-12=36-4х
4x-8-12=36-4x
4x+4x=36+20
8x=56
x=56:8
x=7
9х-17/2 -5х-4=1

4x=1+8,5+4
4x=13,5
x=13,5:4
x=3,375
