y + 35 = ( y ) + ( y - 31 )
y + 35 = 2y - 31
Add both sides 31
y + 35 + 31 = 2y - 31 + 31
y + 66 = 2y
Subtract both sides y
y - y + 66 = 2y - y
y = 66
In mathematical expression, it would be: x - y/2
Hope this helps!
Answer: B
Step-by-step explanation:
x+9<78 => x< 78-9=> x< 69 => b right
Answer:
t+3r
Step-by-step explanation:
This is a one step solution
All you do is add like terms
In this case the only like terms are the varibles r
2r+(t+r)
so if you add all of the rs together there would be 3rs
So the rest of the problem would continue as normal while bringing the 3r to the end
t+3r
Answer:
D
Step-by-step explanation:
