Answer 2

А) -3,2+x=5,2
x=5,2+3,2
x=8,4

б) 6,7+y=4,3
y=4,3-6.7
y=-2,4

Answer 3

To solve the equations, we'll isolate the variable on one side of the equation. Let's solve for x in the first equation and y in the second equation.

a) -3.2 + x = 5.2

Step 1: Add 3.2 to both sides to isolate x on one side. x = 5.2 + 3.2 x = 8.4

So, the value of x is 8.4.

b) 6.7 + y = 4.3

Step 1: Subtract 6.7 from both sides to isolate y on one side. y = 4.3 - 6.7 y = -2.4

So, the value of y is -2.4.
