(134-x)-583=426

134 – x – 583 = 426

– x = 426 + 583 – 134

-x = 875

x = -875

(208+x)-416=137

208 + x – 416 = 137

x = 137 + 416 – 208

x = 345

(x-506)+215=429

x – 506 + 215 = 429

x = 429 – 215 + 506

x = 720

(y-164)+308=500

y – 164 + 308 = 500

y = 500 – 308 + 164

y = 356

(942-a)-126=254

942 – a – 126 = 254

– a = 254 + 126 – 942

-a = -562

a = 562

(801-b)-224=368

801 – b – 224 = 368

– b = 368 + 224 – 801

-b = -209

b = 209

475-(x-671)=325

475 – x + 671 = 325

– x = 325 – 671 – 475

-x = -821

x = 821

972-(y-504)=284

972 – y + 504 = 284

– y = 284 – 504 – 972

-y = -1192

y = 1192

403-(634-a)=336

403 – 634 + a = 336

a = 336 + 634 – 403

a = 567

643-(581-b)=292

643 – 581 + b = 292

b = 292 + 581 – 643

b = 230

987-(x+364)=519

987 – x – 364 = 519

– x = 519 + 364 – 987

-x = -104

x = 104

3128-(m+425)=1509

3128 – m – 425 = 1509

– m = 1509 + 425 – 3128

-m = -1194

m = 1194
