The equation is already factored so, set each factored form to 0.
(x-3)=0 (4x+1)=0
Then, solve each equation.
x-3=0 4x+1=0
+3 +3 -1 -1
______ ______
x=3 4x=-1
--- ---
4 4
______
x=-1/4
So x could be either 3 or -1/4.
Answer:
1.73
Step-by-step explanation:
So, let's set this up:
0.04x+0.05y=1100
0.05x+0.04y=1150
Let's multiply each equation by 100:
4x+5y=110000
5x+4y=115000
Now let's add those together:
9x+9y=225000
And we need to find x+y, so we just divide by 9 and get 25,000
