To solve for y in this, you just substitute one equation for the value of y.

-3x+11=2x+1
5x=10
x=2

Then to get the x you substitute 2 into x in either equation.

2=2x+1
1=2x
1/2=x

Answer:

x = 2

Given:

y = -3x + 11

y = 2x + 1

Step-by-step explanation:

=  >  - 3x + 11 = 2x + 1 \\  \\  =  >  - 3x - 2x = 1 - 11 \\  \\  =  >   \cancel{- }5x = \cancel{  - }10 \\  \\  =  > 5x = 10 \\  \\  =  > x =  \frac{10}{5}  \\  \\  =  > x = 2

Please answer this this question is a motion problem:
mr_godi [17]
T1 + t2 = 2h and 30min;
t1 * 600 = t2 * 400 => t2 = (3/2) * t1;

then, t1 +  (3/2) * t1 = 2h and 30min => 2t1 + 3t1 = 5h => 5*t1 = 5h => t1 = 1h => t2 = 1h and 30 min;

The distance is 2 * 1 * 600 = 1200miles;

alexdok [17]

1,995,000

The number after the thousands place is 2, which is less than 5 so the thousands place is rounded to 5,000 instead of 6,000.
