To eliminate a cariable in a system of equations, we multiply the variable by a factor that will make both coefficients of the variable to be equal.
Thus, we multiply the coefficient of y in the second equation by a factor that will make it equal to the coefficient of y in the first equation. i.e. multiply 1/2 by a factor that makes it equal to 3/4. and the factor is 3/2.
Therefore, the third option is the correct answer.
Answer:
x = 28.06
Step-by-step explanation:
-12.11-10.5=75.6-3.5x
Put all the integers on one side and X on the other.
-12.11 - 10.5 - 75.5 = -3.5x
-98.21 = -3.5x
-98.21/-3.5 = x
x = 28.06
Answer:
All
Step-by-step explanation:
Planet A, because 7 x 10 > 5 x 10, the 28 is also bigger than 26. The numbers means 10 x 10 x 10 x 10... and so on to 28 or 26 (whatever the number is)
