6x+7y =59…(1)
4x+5y =41…(2)
(1)x4 : 24x + 28y = 236 …(3)
(2)x6: 24x +30y =246 …(4)
(4) - (3) :
(24x + 30y) - (24x+28y) = 246 - 236
2y= 10
y=5
subs y=5 into (1)
6x + 7(5) =59
6x+35=59
6x=24
x= 4
So x=4 y=5
Hope i can help u
The anwser is 5x-3 because you remove the parentheses and pair like terms
All right i just earned that today!
This is the formula An = A1 + ( n-1 )D
You would take A19 = -1 + ( 19 - 1 ) -4
-1 + 18(-4)
-1 + -72
-73
Hope that helped!

Answer:
x = 24°
Step-by-step explanation:
<em>Here's</em><em> your</em><em> solution</em>
<em> </em> => (4x - 2) + (3x + 14) = 180°
=> 7x + 12 = 180°
=> 7x = 180° - 12°
=> 7x = 168°
=> x = 168°/7
=> x = 24°
hope it helps
