Question

A) x + (-3,2)=9,5 b) y - 2,6 = -1,74 в) (4,5 - y) * 5,8 = 8,7

Answer 1

1) х=9,5+3,2
х=12,7
2) у=-1,74+2,6
у=0,86
3) 4,5-у=8,7/5,8
4,5-у=1,5
у=1,5-4,5
у= -3

Answer 2

To solve these equations for the variables x and y, follow these steps:

A) x + (-3,2) = 9,5:

First, simplify the equation by adding 3.2 to both sides to isolate x:

x + (-3.2) + 3.2 = 9.5 + 3.2

x = 12.7

So, the solution for equation A is x = 12.7.

B) y - 2.6 = -1.74:

To isolate y, add 2.6 to both sides:

y - 2.6 + 2.6 = -1.74 + 2.6

y = 0.86

The solution for equation B is y = 0.86.

C) (4.5 - y) * 5.8 = 8.7:

First, divide both sides by 5.8 to isolate the expression (4.5 - y):

(4.5 - y) * 5.8 / 5.8 = 8.7 / 5.8

4.5 - y = 1.5

Now, subtract 4.5 from both sides to solve for y:

• y = 1.5 - 4.5

• y = -3

To find the value of y, multiply both sides by -1:

y = 3

So, the solution for equation C is y = 3.
