Question

74,5−(t−0,37)=31 (x−18,2)+0,32=4,2

Answer 1

1) -t = -43,87
T= 43,87
Тут все просто
2) x -18,2+0,32 = 4,2
X-17,88=4,2
X= 22,08

Answer 2

It looks like you've provided two equations with variables. Let's solve them step by step.

Equation 1: 74.5 - (t - 0.37) = 31

First, distribute the negative sign: 74.5 - t + 0.37 = 31

Combine like terms: 74.87 - t = 31

Now, isolate the variable t by subtracting 74.87 from both sides: -t = 31 - 74.87 -t = -43.87

Multiply both sides by -1 to solve for t: t = 43.87

Equation 2: (x - 18.2) + 0.32 = 4.2

Combine the terms on the left side: x - 18.2 + 0.32 = 4.2

Combine like terms: x - 17.88 = 4.2

Now, isolate the variable x by adding 17.88 to both sides: x = 4.2 + 17.88 x = 22.08

So, the solutions are: t = 43.87 x = 22.08
