Question

323+(x-75)=186

231-(x-6)=1339:13

Answer 1

323+(x-75)=186

x-75=186-323

x-75=-137

x=-137+75

x=-62

231-(x-6)=1339:13

231-(x-6)=103

x-6=231-103

x-6=128

x=128+6

x=134

Answer 2

323 + ( x-75 ) = 186

x - 75 = 323 - 186

x -75 = 137

x = 137 + 75

x = 212

231 - ( x-6 ) = 1339 : 13

231 - ( x-6 ) = 103

x - 6 = 231 - 103

x - 6 = 128

x = 128 + 6

x = 134
