Find the equation of the line which passes through the point (−2,−5) and is parallel to the line −3x+5y=−4.
leonid [27]
-3x+5y=-4
5y=3x-4
Y=3/5x-4/5


When it parallel to the line y=3/5x-4/5

It can be y=-3/5x+b

-5=6/5+b

B=-5-6/5=-25/5-6/5=-31/5

Y=-3/5x-31/5

3/5x+y=-31/5

Multiply 5

3x+5y=-31

What is the value of x in the equation 3x-4y=65, when y=4?
Softa [21]

Answer:

\boxed{ \bold{ \huge{ \boxed { \sf{x = 27}}}}}

Step-by-step explanation:

Given, value of y = 4

To find : Value of x

\sf{3x - 4y = 65}

plug the value of y

\dashrightarrow{ \sf{3x - 4 \times 4 = 65}}

Multiply the numbers : 4 and 4

\dashrightarrow{ \sf{3x - 16 = 65}}

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

\dashrightarrow{ \sf{3x = 65 + 16}}

Add the numbers : 65 and 16

\dashrightarrow{ \sf{3x = 81}}

Divide both sides by 3

\dashrightarrow{ \sf{ \frac{3x}{3}  =  \frac{81}{3} }}

Calculate

\dashrightarrow{ \sf{ x = 27}}

Hope I helped!

Best regards! :D
