Question

(X-348)+159=601 468-(259-x)=382' (x-12)*8=56 9y-54=162 (y+25):8=16 38x+15=91 123-4x=749

Answer 1

Х - 348 + 159 = 601
х = 601 - 159 + 348
х = 790
-------------------
468 - (259 + х )= 382
(259 +х) = 468 - 382
259 + х = 86
х = 86 - 259
х = - 173
---------------------------
8х - 96 = 56
8х = 56 + 92
8х = 152
  х = 19
--------------------------
9у - 54 = 162
9у = 162 + 54
9у = 216
у = 24
-----------------------
(у + 25) = 16 * 8
у + 25 = 128
у = 128 - 25
у = 103
----------------------------
38х = 91 - 15
38х = 76
    х = 2
------------------------------
4х = 123 - 749
4х = - 626
  х = - 156,5
