Answer:

No solution

Step-by-step explanation:

If you develop a little both sides of the equation you will have

6x-10=6x-12

Which leaves you to anything

And since you dont have anything else to use as an equation, there is nothing else we can do about

2x – Зу = -1 + 3x+3y= 26 ОА. бу = 25 ОВ. 5х = 27 Ос. 5х = 25 OD. 5x - бу = -27

Brilliant_brown [7]

Answer:

C. $5x=25$

Step-by-step explanation:

Given:

$2x-3y=-1\\3x-3y=26$

Add the two equations, we get

$2x-3y+3x+3y=-1+26\\(2x+3x)+(-3y+3y)=25\\5x+0=25\\5x=25$

Therefore, the correct option is option C.

For the table, y = 9x.

so the price of a short cake is $9

For the graph, y = 4x
so the price of a sweet bread is $4

9-4 = 5

the short cake is $5 more than the sweet bread
