Question

Plz help me i cant figure this out and explain the steps pls

Answer 1

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
