Question

(456 + 112) - x = 400
x - (203 + 303) = 34
(283 - x) - 33 = 0
382 - (x + 42) = 111
(536 + x) - 420 = 116
437 - (227 + x) = 0
468 - 217 - x = 51

Answer 1

(456+112)-x=400
568-x=400
x=568-400
X=168

X-(203+303)=34
X-506=34
X=506+34
X=540

(283-x)-33=0
283-x=0+33
283-x=33
X=283-33
X=250

382-(x+42)=111
X+42=382-111
X+42=271
X=271-42
X=229

(536+x)-420=116
536+x= 116+420
536+x=536
X=536-536
X=0

437-(227+x)=0
227+x=437-0
227+x=437
X=437-227
X=210

468-217-x=51
251-x=51
X=251-51
X=200
