What is the value of y in the equation 5x + 2y = 20, when x = 0.3? 0 2.5 2.8 O 9.25 O 10.75​

O 9.25

Explanation:

The following mathematical equation is given in this question:

5x + 2y = 20

Using this equation, we're asked to find the value of y when x = 0.3. Hence, we substitute 0.3 for x in the equation as follows:

5x + 2y = 20

5 (0.3) + 2y = 20

1.5 + 2y = 20

Collect like terms

2y = 20 - 1.5

2y = 18.5

Divide both sides by 2

y = 18.5/2

y = 9.25

Therefore, y = 9.25 when x = 0.3
