Question

what is y equal to
5x+3y=40, when x=2

Answer 1

Answer:

10 is the value of y. y= 10.

Step-by-step explanation:

Hey there!

Putting value of x in the given equation.

we get,

5*2 + (3y) = 40

so, 10 +(3y) = 40

Therefore, 3y = 40-10

3y = 30

it means y= 30/3 = 10.

Answer 2

Here is the answer to your question!!

Given: What is the value of y in the equation 5x + 3y = 40, when x= 2.

Solution;

5x + 3y = 40

We have been given x = 2

So, by putting the value of x in the equation;

5(2) + 3y = 40

Simplifying the equation =

5(2) + 3y = 40

=> 10 + 3y = 40

=> 3y = 40 - 10 = 30

=> y = 30/3 = 10

• So the value of y = 10.

Verification :

Putting the value of y in the equation;

5(2) + 3 (10) = 40

=> 10 + 30 =40

=> 40 = 40

Hence LHS = RHS.

Hope it helped!!
