Answer:
–6x + 2y = 3/2 is Sandra's equation.
Step-by-step explanation:
Given Equation of Tomas is
Solution of equation of Sandra is same as solution of Tomas Equation.
This only possible when ratio of the coefficients of the variable and constant term is equal.
So,
Multiply Tomas equation with 2.
2y= 6x + 3/2
This is one of the equation possible for Sandra's equation
Therefore, –6x + 2y = 3/2 is Sandra's equation.
Answer: 860
move the decimal from 1.900 to the back
1.900-----1900.
then take the imaginary decimal behind 1634. and move it to 3 places to left.
then divide
y= 5 x 60
