2x+2y=10 solve for x
irakobra [83]

Isolate the x. Note the equal sign. What you do to one side you do to the other.


Subtract 2y from both sides


2x + 2y (-2y) = 10 (-2y)


2x = 10 - 2y


Isolate the x, divide 2 from both sides and from all terms.


(2x)/2 = (10 - 2y)/2


x = 5 - y


Place the variable in the front


x = -y + 5


x = -y + 5 is your answer


hope this helps

Shkiper50 [21]

Answer:

-10 = a

Step-by-step explanation:

17 = a - 3 - За

Combine like terms

17 = -3 -2a

Add 3 to each side

17+3 = -3-2a+3

20 = -2a

Divide by -2

20/-2 = -2a/-2

-10 = a
