Step-by-step explanation:

Solve by substitution (Assumption)

Given:

[1] y = 6x - 11

[2] -2x-3y = -7

Using [1] substitute (6x-11) for y in [2]

[3] -2x-18x+33=-7

Simplifying

[4] 20x=40

[5] x = 2

Using [5] substitute 4 for x in [1]

[6] y= 12 - 11

[7] y = 1

Solution is (x,y)=(2,1)

Answer:

Yes, this equation has a solution. According to Intermediate Value Theorem at least one solution for [0,2]

Step-by-step explanation:

Hi there!

1) Remember a definition.

Intermediate Value Theorem:

If $f$ is continuous on a given closed interval [a,b], and f(a)≠f(b) and f(a)<k<f(b) then there has to be at least one number 'c' between 'a' and 'b', such that f(c)=k
