Solve the system using substitution

Option B

No solutions

Step-by-step explanation:

We have the following system of equations

   (1)

  (2)

To solve the system using the substitution method, solve the first equation for the variable y

Now substitute the value of y in the second equation

2 is not equal to -9, the system is inconsistent. The system has no solution

No solution

Step-by-step explanation:

Given equations are 2x-y=-6 and -4x+2y=-9.

Now we need to solve that system of equation using substitution method.

solve 2x-y=-6 for y

2x-y=-6

-y=-6-2x

y=6+2x

Plug this value of y into other equation -4x+2y=-9

-4x+2(6+2x)=-9

-4x+12+4x=-9

12=-9

Which is a false equation.

Hence there is no solution to the given system.

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
