59+y = 69 + 63 - 72
27+z=41+37-12
49+x=58+34-29
37+y =74-20+9
1340+x=1278+693
y+5706=8304-1806
274+(112-94)=198+z

Answer 1

2. $59 + y = 69 + 63 - 72 \\ 59 + y = 69 + 9 \\ y = 78 - 59 \\ y = 19 \\ \\ 27 + z = 41 + 37 - 12 \\ 27 + z = 41 + 12 \\ z = 53 - 27 \\ z = 27 \\ \\ 49 + x = 58 + 34 - 29 \\ 49 + x = 58 + 5 \\ x = 63 - 49 \\ x = 14 \\ \\ 37 + y = 74 - 20 + 9 \\ 37 + y = 54 + 9 \\ y = 63 - 37 \\ y = 26 \\ \\ 1340 + x = 1278 + 693 \\ 1340 + x = 1971 \\ x = 1971 - 1340 \\ x = 631 \\ \\ y + 5706 = 8304 - 1806 \\ y + 5706 = 6498 \\ y = 6498 - 5706 \\ y = 792 \\ \\ 274 + (112 - 94) = 198 + z \\ 274 + 19 = 198 + z \\ 293 = 198 + z \\ 198 - 293 = z \\ 95 = z$
