28 divided by 4 = 7
so do 7 * 5 which is 35 so they make 35 cookies in 5 seconds
4x-2=18
-2 on both sides
4x=16
divid by 4 on both sides
x= 4
Answer:
yes
Step-by-step explanation:
Substitute x = 2 and y = 2 into both equations and if both are true then (2, 2) is a solution of the system.
y = x, that is
2 = 2 ← True
x + 2y = 6, that is
2 + 2(2) = 2 + 4 = 6 ← True
Thus (2, 2) is a solution of the system
