Answer:

I think this is the answer. Not sure though.

Step-by-step explanation:

Take 3x, for example

3x will equal to (4x - 10)

So, in other words, the equation is .....

(4x - 10) + 3x = 10

= 7x - 10 = 10

7x = 10 + 10

= 20

x = 20/7

x =  2.85

y = 4x - 10

= (4 x 2.85) - 10

= 11.4 - 10

= 1.4.
