Answer:

The value of x:


  • x=-(13)/(4)

Explanation:

Given the equation


R=4x+6y

substituting the values y=4 and R=11


R=4x+6y


11=4x+6\left(4\right)


11=4x+24


11-24=4x

switching the sides


4x=11-24

Subtract the numbers: 11-24=-13


4x=-13

Divide both sides by 4


(4x)/(4)=(-13)/(4)


x=-(13)/(4)

Therefore, the value of x:


  • x=-(13)/(4)
