The equation is 30x + 25
 since the x is with the 30, that would be the cost per lesson, because you would multiply 30 by the number of lessons(x)

In this equation, you have to treat the number in the bracket first on the basis of BODMAS
15 - [-3]- 4
Note that when two minuses come together the product is a plus sign.
15 +3 - 4
You have to add before you subract
18 - 4 =14
Therefore, 15- [-3] - 4 = 14.

For what value of k will these pairs of simultaneous equations have no solution?
yKpoI14uk [10]
Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=\frac{k+3}{k-12}
Also y=\frac{5k}{k-12}
We can not divide with zero.
k-12=0
k=12
For k= 12 equations have no solutions.
