Substitution Form: 2x-3y=2 x+y=-1 x+y=-1 Elimination From: 2x/3 - 4y/5 = 1 and 3x-y=-7

Use substitution to solve the system of equations

Method that must be used is by substitution

So I tried doing the equation out and I got fractions for the ordered pairs. I got x=4/3 and y=20/3. Our teacher has us do checks so when I checked the problem out it didn't work out.

1=sqrt(x+sqrt(x+sqrt(x+sqrt(x+... Using a substition, it seems you can get 1=sqrt(x+1), but that leads to x=0, which seems wrong when you plug it back into the original equation...

How tall is the statue? How tall is the building?

For this problem, I know how to solve it, but can't set it up. I have x+y=3000 0.70x+0.35y=(0.58)(300) but it's quite right. Thanks! A silversmith has two alloys,...

Josie wants to buy Internet access. One service provider charged a flat rate of $34.95/month. A second charges $25/month plus $0.33/hour. For what number of hours per month should Josie choose the...

when integrating ∫sin3xdx, a good first move would be to: a) use u-substitution, letting u=sinx, and then integrating ∫u3du b) use u-substitution, letting u=sin2x c)...

When integrating ∫esinxcosdx, a good choice to use for your u-substitution would be which of the following: a) u=cosx b) u=sinx c) u=esinx

if the substitution √(x)=sin(y) is made into the integrand of (with the upper limit of: 1/2 and the lower limit of: 0) ∫ ( (√(x) )/( (√(1-x) )dx , the resulting integral is _______________...
