a) \(\text{ x + 175 + 1225 = 1482}\)
\(x+175=1482-1225\)
\(x+175=257\)
\(x=257-175\)
\(x=82\)
b) \(\text{ x – 850 + 750 = 1000}\)
\(x-850=1000-750\)
\(x-850=250\)
\(x=1100\)
c) \(\text{ 999 – x = 999 - 921}\)
\(999-x=78\)
\(x=999-78\)
\(x=921\)
a) x + 175 + 1225 = 1482
x + (175 + 1225)= 1482
x + 1400 = 1482
x = 1482
b)x – 850 + 750 = 1000
x - ( 850 + 750) = 1000
x - 1600 = 1000
x = 1000 + 1600
x = 2600
c)999 – x = 999 - 921
999 – x = 78
x = 999 –78
x = 921
a) x + 175 + 1225 = 1482 x + 175 = 1482 − 1225 x + 175 = 257 x = 257 − 175 x = 82
b) x – 850 + 750 = 1000 x − 850 = 1000 − 750 x − 850 = 250
