Question

А)11y-(3y+12)=4(2y-3) б)8x-13+5x-5

Answer 1

11y-(3y+12)=4 (2y-3)
11y-3y-12=8y-12
11y-3y-8y=-12+12
0=0

Answer 2

a)

To solve the equation, we need to simplify and then isolate the variable, y:

11y - (3y + 12) = 4(2y - 3)

11y - 3y - 12 = 8y - 12

8y - 12 = 8y - 12

We can see that the equation is an identity, which means that any value of y will satisfy it. Therefore, the solution is all real numbers.

b)

To solve this equation, we need to combine like terms:

8x - 13 + 5x - 5 = 13x - 18

Now, we can simplify further by adding 18 to both sides:

13x - 18 + 18 = 13x

13x = 13x

We can see that the equation is an identity, which means that any value of x will satisfy it. Therefore, the solution is all real numbers.
