Question

0,87x-0,9x+1,3x=-15,24

Answer 1

0,87x-0,9x+1,3x=-15,24
x*( 0.87 - 0.9 + 1.3 ) = -15.24
1.27*x = - 15.24
x = - 15.24/1.27
x = - 12

Answer 2

0.87x-0.9z+1.3x=-15.24
x=-12

Answer 3

To solve the equation, combine like terms on the left-hand side:

0.87x - 0.9x + 1.3x = -15.24

To combine the x terms, first, subtract 0.9x from 0.87x:

(0.87 - 0.9)x + 1.3x = -15.24

Next, subtract 0.9 from 0.87:

(-0.03)x + 1.3x = -15.24

Now, combine the x terms:

(1.27)x = -15.24

To isolate x, divide both sides by 1.27:

x = -15.24 / 1.27

Now, calculate the value of x:

x ≈ -12.00

So, the solution to the equation is approximately x = -12.00.
