Question

Решите уравнение:
1)x+32=171
2)463-y=219
3)(246+a)-42=643

Answer 1

1)х+32=171;
x=171-32;
x=139.

2)463-y=219;
y=463-219;
y=244.

3)(246+a)-42=643;
246+a=643+42;
246+a=685;
a=685-246;
a=439

Answer 2

1) x+32=171
x=171-32
x=139

2) 463-y=219
y=463-219
y= 244

3) (246+a)-42=643
246+a-42=643
204+a=643
a=643-204
a=439
