Question

1) （94,2-a)-1,26=3,254 2) 40,3-(63,4-a)=36,62

Answer 1

1) (94,2 - а)-1,26=3,254
94,2 - а = 3,254 + 1,26
94,2 -а = 4,514
-а = 4,514 - 94,2
-а = -89,686
а = 89,686

2)40,3 - (63,4 - а) = 36,62
40,3 - 63,4 + а = 36,62
а = 36,62 - 40,3 + 63,4
а = 59,72

Answer 2

1)
（94,2-a)-1,26=3,254
94,2-a-1,26=3,254
92,94-a=3,254
a=92,94-3,254
a=89,686


2)
 40,3-(63,4-a)=36,62
40,3-63,4+a=36,62
a-23,1=36,62
a=36,62+23,1
a=59,72

Answer 3

To solve the given equations, we need to find the value of the variable "a". Let's work through each equation step by step:

1. $94.2 - \frac{1}{26} = 3.254$

To solve for "a," first, we need to isolate the variable on one side of the equation. Let's get rid of the constant terms on the left side.

$94.2 - 3.254 = \frac{1}{26}$

$90.946 = \frac{1}{26}$

Now, to find "a," we'll isolate it by multiplying both sides by 26:

$26 \times 90.946 = 1$

$2363.596 = 1$

However, this leads to a contradiction. The equation is inconsistent and has no solution. Please double-check the equation or provide additional information if there was a mistake.

2. $40.3 - (63.4 - a) = 36.62$

To solve for "a," let's simplify the equation step by step:

First, perform the operation inside the parentheses:

$40.3 - 63.4 + a = 36.62$

Next, combine the constant terms on the left side:

$-23.1 + a = 36.62$

To isolate "a," we need to get rid of -23.1 on the left side. We can do this by adding 23.1 to both sides of the equation:

$-23.1 + a + 23.1 = 36.62 + 23.1$

$a = 59.72$

So, the value of "a" that satisfies the equation is $a = 59.72$.
