Answer:
X=-25/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/5x+1/2-1/2x=1/2x+3-1/2x
-3/10x+1/2=3
Step 3: Subtract 1/2 from both sides.
-3/10x+1/2-1/2=3-1/2
-3/10x=5/2
Step 4: Multiply both sides by 10/(-3).
(10/-3)*(-3/10)=(10/-3)*(5/2)
X=-25/3
Hope that helps :D
Sum of interior angles of polygon:
= 180(n - 2)
= 180(5-2)
= 180(3)
= 540
so
2x = 540 - (90+100+70)
2x = 540 - 260
2x = 280
x = 140
answer
x = 140
Hope it helps
★ Linear Reduction ★
6a + ( 8b + 2a ) = 6a + ( 2a + 8b )
6a + 8b + 2a = 6a + 8b + 2a
Hence , a = b = c is the only possible set available in real numbers
(a = b = c) ∈ R
