Answer:
x = 5
y = 4
Step-by-step explanation:
just substitute the value of one variable into the other
-x +y = -1
or y = -1 +x <-------- (i just added x to the right side)
now u know what y is equal to, just substitute that value into the first equation
2x - (-1+x) = 6 <-------- instead of y, i put the value of y from the 2 equation
NOW SOLVE FOR X!
2x +1 -x = 6
x + 1 = 6
x = 5
now solve for y since you have the value of x
y = -1 + x
or y = -1 + 5
y = 4

Answer:
1.36+3+(32)(2)
=57
error is that 6 is the wrong answer
1 inch=1515 miles
X inches= 385 miles
so 1515 is 3.935 times bigger than 385 miles.
meaning that 1 inch is also 3.935 times bigger than X inches.
to find X we just divide 1 by 3.935
which is: 0.254 inches
