Answer:
x=20
Step-by-step explanation:
Substitute 15 for y
it will be 2/3 multiplied by 15 then you get 10
you add 10 to 30 getting 40
then you divide 40 by 1/2 getting 20
:)))
Answer:
x = 80
Step-by-step explanation:
First, plug the 15 into the y.
[tex]1/2x - 2/3(15) = 30[/tex]
Use PEMDAS to solve the parentheses, 2/3 of 15 is 10.
[tex]1/2x - 10 = 30[/tex]
Add 10 to both sides of the equation.
[tex]1/2x = 40[/tex]
Divide each side by 1/2 (or multiply by it's reciprocal, which is 2)
That will get you your answer of x = 80
