Answer:
Step-by-step explanation:
0
You would substitute 0.8 in for y and to get the equation 4x+8(0.8)=40. Then, you would simplify and get 4x+6.4=40. Next you would isolate x by subtracting 6.4 from both sides and get the equation 4x=33.6 and then you would divide both sides by 4 to get x=8.4.
The answer is : x=8.4
X=2y/3
x+y=30
plug in the value of x in the second equation to have one variable in the equation...
2y/3+y=30
5y/3=30
then multiply 3 on both sides...
5y=90
divide by 5 on both sides...
y=18
and to solve for x you have to plug in y on either equation...
1st way to solve for x:
x+18=30
subtract 18 on both sides...
x=12
2nd way to solve for x:
x=(18)2/3
you then solve...
x=36/3
x=12
answer: 12,18
