To solve this equation, we must substitute in 0.3 for the value of x and then solve the equation for y.
5(0.3) + 2y = 20
To simplify, we begin by multiplying the two numbers on the left side of the equation.
1.5 + 2y = 20
Next, we should subtract 1.5 from both sides of the equation to get the variable term alone.
2y = 18.5
Finally, we should divide both sides of the equation by 2 in order to get the variable y completely alone on the left side of the equation.
y = 9.25
Therefore, the value of y is 9.25.
Hope this helps!
