Sarah spent $1,083 because $57*38=$2,166 and $2,166/2=$1083
Answer:
x + y = 8
20x + 110y = 340
Step-by-step explanation:
X = unknown number
10x - 16 = 2x
Subtract 10x from both sides to isolate the variable on the right side of the equation.
-16 = -8x
Divide both sides by -8 to get x alone.
2 = x

-2x + (5/-5x) - 7 -
-2x -x -7 =
-3x - 7
Thank you,
