Question

1)4x - 39 = 5x +87 +2x;
2) -15y -109 +269 +27y;
3)18z + 600 =29x +152;

Answer 1

1) 4x-5x-2x=87+39       -3x=126     x=-42
2) -15y-27y=269+109     -42y=378     y=-9
3) 18z-29z=152-600     -11z=-448    z=448/11

Answer 2

4х-5х-2х=87+39
-3х=126
х=126:(-3)
х= -42

-15у+27у-109+269=12у+160=4(3у+40)

18z-29z=152-600
-11z= -448
z= -448:(-11)
z=40 8/11
