Question

1) (х - 4) = 2 3) (3 + х) = 1,5 2) (у + 5 ) = 3 4) (7 - у) = - 2

Answer 1

Ответ:

1) (х - 4) = 2

x-4=2

x=2+4

x=6

2) (у + 5 ) = 3

у+5=3

y=3-5

y=-2

3) (3 + х) = 1,5

3+х=1,5

x=1.5-3

x=-1.5

4) (7 - у) = - 2

7-у=-2

-y=-7-2

-y=-9

y=9

Answer 2

It looks like you've written a set of equations with variables x and y. Let's solve each equation:

1. (x - 4) = 2 To solve for x, add 4 to both sides of the equation: x - 4 + 4 = 2 + 4 x = 6

So, the solution to the first equation is x = 6.

2. (y + 5) = 3 To solve for y, subtract 5 from both sides of the equation: y + 5 - 5 = 3 - 5 y = -2

The solution to the second equation is y = -2.

3. (3 + x) = 1.5 To solve for x, subtract 3 from both sides of the equation: 3 + x - 3 = 1.5 - 3 x = -1.5

The solution to the third equation is x = -1.5.

4. (7 - y) = -2 To solve for y, subtract -2 from both sides of the equation: 7 - y + 2 = -2 + 2 7 - y = 0

Now, subtract 7 from both sides of the equation: 7 - y - 7 = 0 - 7 -y = -7

To isolate y, divide both sides by -1 (remember that dividing by a negative number flips the inequality sign): -y / -1 = -7 / -1 y = 7

So, the solution to the fourth equation is y = 7.
