Answer:
48
Step-by-step explanation:
(204-x)/2=78
or, 204-x=156
or, x=204-156
or, x=48
Ok so the first step to solve it is subtraction then it’s multiplication then additions
Okay so first let’s set one of the two equations equation to one of the two variables
I’m going to pick the second equation and y
So
x+y=10
y=10-x
Now let’s bring the other equation in and substitute y for 10-x
2x+3y=45
2x+3(10-x)=45
Now solve for x
2x+3(10-x)=45
2x+30-3x=45
-x+30=45
-x=15
x=-15
Okay so now we have x = -15 now let’s find y by using the original equation I moved around and pigging in y like
y=10-x
Plug in x
y=10-(-15)
y=10+15
y=25
So now that I look back at the program you only needed x but her is x and y I hope I helped
