Here are the step for solving this:
1. 3y + 5 > 23
-5 -5
3y/3 > 18/3
y > 6
In words what you are doing is getting y by itself on one side. Subtract the 5 to undo the adding of 5 first. Then, divide both sides by 3.
The equal of x+7=26 so it’s definitely (a)
Hello! 36 does not belong in the pattern. The pattern is multiply by 2, but 36 doesn’t belong, because half of it is 18 and 18 is not an option. The other numbers go together to make that pattern of multiplying by 2. The answer is 36.
Answer:
i think that it is b and c
Step-by-step explanation:
X + 2y = 50
-2x + 3y = 40
5x + 5y + 5z = 300
================
x + 2y = 50 ....multiply by 2
-2x + 3y = 40
--------------------
2x + 4y = 100 (result of multiplying by 2)
-2x + 3y = 40
------------------add
7y = 140
y = 140/7
y = 20 <==
x + 2y = 50
x + 2(20) = 50
x + 40 = 50
x = 50 - 40
x = 10 <==
5x + 5y + 5z = 300
5(10) + 5(20) + 5z = 300
50 + 100 + 5z = 300
150 + 5z = 300
5z = 300 - 150
5z = 150
z = 150/5
z = 30 <==
solution : (10,20,30)...x =10, y = 20 , z = 30
