1) x + 75 = 125x = 125 - 75x = 50
2) x * 10 = 250x = 250 / 10x = 25
3) x / 10 = 250x = 250 * 10x = 2500
4) x / 7 = 140x = 140 * 7x = 980
5) 140 / x = 7x = 140 / 7x = 20
6) 32 / x = 32x = 32 / 32x = 1
7) 32 * x = 32x = 32 / 32x = 1
8) x - 75 = 125x = 125 + 75x = 200
Итак, решения уравнений в парах следующие:1) x = 50 и x = 2002) x = 25 и x = 20003) x = 25004) x = 9805) x = 206) x = 17) x = 1
1) x + 75 = 125
x = 125 - 75
x = 50
2) x * 10 = 250
x = 250 / 10
x = 25
3) x / 10 = 250
x = 250 * 10
x = 2500
4) x / 7 = 140
x = 140 * 7
x = 980
5) 140 / x = 7
x = 140 / 7
x = 20
6) 32 / x = 32
x = 32 / 32
x = 1
7) 32 * x = 32
x = 32 / 32
x = 1
8) x - 75 = 125
x = 125 + 75
x = 200
Итак, решения уравнений в парах следующие:
1) x = 50 и x = 200
2) x = 25 и x = 2000
3) x = 2500
4) x = 980
5) x = 20
6) x = 1
7) x = 1
