Answer:
10 because it goes by 2 so 5 x2 is 10 so 3 x2 is 6 so its x 2
Answer:
x/5 - 7 = 8
Step-by-step explanation:
Answer:
x 2 y -4
Step-by-step explanation:
13x = -54 -20y give it is A
-10x = 60 + 20y give it is B
A + B the sum of the left side of equation is equal to the sum of the right side of equation
13 + (-10x) = -54 -20y + 60 + 20y
3x = 60-54
3x = 6
x=2
so put the x value in A or B equation you can receive y value (B is easier)
y = -4
