answer:

x = ( -y + 49 )/ 8

step-by-step explanation:

good morning!

lets start off by adding both equations

4x + 16y = 32

4x + y = 17

+ ____________

8x + y = 49 <--------- our new starting equation

first we need to move the variable ( y ) to the other side of the equation, in other words separate them

8x = 49 + y

then lets rearrange the expression

8x = −y + 49

we need to still divide both sides by 8 to get ( x ) by itself

8x/ 8 = ( −y + 49 )/ 8

turning this equation into your new answer!

x = ( -y + 49 )/ 8   <-------------- our answer!

i hope this helps you! and if i read the question/ or made it a little confusing then please let me know, i hope you have a good rest of you day :)
