Plzzz help ty What is the difference of the values of the two variables in this system of equations?
y= 2x + 1
x + 3y = 10

Α. 0

B. 1

C. 2

D. 3

C

Step-by-step explanation: y = 2x + 1, x + 3y = 10 in these two equations you can put y = 2x + 1 in 3y in x + 3y = 10 so it would be x + 3(2x + 1) = 10,

x + 6x + 3 = 10, 7x = 7 so x = 1 and when we put the value of x in y = 2x + 1, it would be y = 2(1) + 1 so y = 3. difference would be 3 - 1 = 2 so it is C

angle addition postulate

2x=56
