(1) 3.5X+1.8=12.3 (5) X+X=21 (6) X+X=
(7) 3.6X÷2=2.16 (8) X+X= (2) 0.8X-4=1.6
(3) 5X÷2=10 (4) X-0.25X=3 (9) X-X=
(10) X-= (11) 2X+7X= (12) +X=
(13) X= (14) X= (15) X=10
(16) 180+6X=330 (17) 2.2X-1=10 (18) X-0.8X=10
(19) 15X÷2=60 (20) 4X+X=3.15 (21)3.4X+1.8=8.6
(22) 5X-X=2.4 (23) 1.5X-X=1 (24) 6.6X-6X=1.8
