Решите уравнение: 1) (1,34+x)-58,3=4,26 2) (94,2-a)-1,26=3,254 3) 4,75-(x-0,67)=3,025; 4) 40,3-(63,4-a)=36,62.

1) (1,34 + x) - 58,3 = 4,26;

1,34 + x = 4,26 + 58,3;

1,34 + x = 62,56;

х = 62,56 – 1,34;

х = 61,22.

2) (94,2 - a) - 1,26 = 3,254;

94,2 – a = 3,254 + 1,26;

94,2 – a = 4,514;

а = 94,2 – 4,514;

а = 89,686.

3) 4,75 - (x - 0,67) = 3,025;

x - 0,67 = 4,75 – 3,025;

x - 0,67 = 1,725;

х = 1,725 + 0,67;

х = 2,395.

4) 40,3 - (63,4 - a) = 36,62;

63,4 – a = 40,3 – 36,62;

63,4 – a = 3,68;

а = 63,4 – 3,68;

а = 59,72.
