So the first two line segments added together equals the full line segment. So, 8y + 5 + 7y = 13y + 25
15y + 5 = 13y + 25
2y = 20
y = 10
and 
use the second expression to calculate the left-hand side of the first equation:
Add 10 to both sides if this equation to get
and divide both sides by 2
this proves that x = 17, give the two initial equations
Answer:
X=3
Step-by-step explanation:
2(4x-3)-t=4+2x
multiply parentheses by 2
8x-6-8=4+2x
Calculate
8x-14=4+2x
Move terms
8x-2x=4+14
Calculate the sum after collecting like terms
6x=18
Divide both sides by 6
x=3
Answer:
C
Step-by-step explanation:
P(n,r)=P(13,9)
=13!(13−9)!
=2.594592E+8
= 259459200
Answer:
x > 5
Step-by-step explanation:
14 - 3x < -1
-3x < -15
x > 5
