Question

A-80=320+350. 590-x=110+260. x+120=900-540. 480+b=960-150

Answer 1

a-80=320+350

a-80=670

a=670+80

a=750

750-80=320+350

Answer 2

a-80=320+350

a-80=670

a=670+80

a=750;

590-x=110+260

590-x=370

x=590-370

x=220;

x+120=900-540

x+120=360

x=360-120

x=240;

480+b=960-150

480+b=810

b=810-480
