Answers:
Question 1: y = 5
Question 2: x < 1.6666667
Explanation:
Question 1:
We have the equation 5x - 2y = 30.
Now, we have to subtract 5x from both sides of the equation.
-2y = -5x + 30
Next, we have to divide the numbers.
y = 2.5x - 15
Make sure to put in the value of x.
y = 2.5 (8) - 15
We have to multiply now.
y = 20 - 15
20 - 15 = 5,
y = 5
Question 2:
We have the equation 12x - 4 < 16.
Add 4 to both of the sides of the equation.
12x < 20
Divide the numbers.
x = 20 ÷ 12
20 ÷ 12 = 1.66666667
Hope this helps you!
