Question

x=10
3x+5y=20
in the system of equations, what is the value of y

Answer 1

3(10) + 5y = 20
5y = 20 - 30
5y = - 10
y = - 2

Answer 2

The value of y in the system of equations x = 10 and 3x + 5y = 20 is -2

How to solve for y?

The system of equations is given as:

x = 10

3x + 5y = 20

Substitute 10 for x in the second equation

3 * 10 + 5y = 20

Evaluate

30 + 5y = 20

Subtract 30 from both sides

5y = -10

Divide both sides by 5

y = -2

Hence, the value of y in the system of equations is -2
