Answer:

[tex] \boxed{ \bold{ \huge{ \boxed { \sf{x = 27}}}}}[/tex]

Step-by-step explanation:

Given, value of y = 4

To find : Value of x

[tex] \sf{3x - 4y = 65}[/tex]

plug the value of y

[tex] \dashrightarrow{ \sf{3x - 4 \times 4 = 65}}[/tex]

Multiply the numbers : 4 and 4

[tex] \dashrightarrow{ \sf{3x - 16 = 65}}[/tex]

Move 16 to right hand side and change it's sign

[tex] \dashrightarrow{ \sf{3x = 65 + 16}}[/tex]

Add the numbers : 65 and 16

[tex] \dashrightarrow{ \sf{3x = 81}}[/tex]

Divide both sides by 3

[tex] \dashrightarrow{ \sf{ \frac{3x}{3} = \frac{81}{3} }}[/tex]

Calculate

[tex] \dashrightarrow{ \sf{ x = 27}}[/tex]

Hope I helped!

Best regards! :D

Answer:

Step-by-step explanation:

-4 x 4=-16 so you add the 16 to the 65 and get 81 so then you divide the 3 from the x so it would be 81/3=27
