I assume that the "d2" was a typo as a problem such as this with 2 variables would require a <em>system of equations</em>.
I also assume that the ? is a typo and will replace it with 0, however you can repeat my steps with whatever it actually it.
I assume that the correct form is 2 + 3a + 6 + a = 0
2 + 3a + 6 + a = 0
Combine like terms
8 + 3a + a = 0
8 + 4a = 0
move 8 to other side
4a = -8
a= -8/4
a = -2*
plug this value of a into the original equation
2 + 3(-2) + 6 + (-2) = 0
The statement is true!
<em>* This probably isn't your answer! Repeat my steps with whatever the value of "?" is.</em>
Answer:
If the two numbers are x and y, then:
x + y = 8
18 - 2x = 4y - 2.
When we subtract y from both sides in our first equation we get:
x = 8 - y, so:
18 - 2(8 - y) = 4y - 2
18 - 16 + 2y = 4y - 2
2 + 2y = 4y - 2
2y = 4
y = 2
Since x + y = 8, and y = 2, x = 6, and since 6 > 2, the larger number is 6.
<span>supplementary of two angles whose sum is 180</span>
so
<span>∠1 + ∠2 = 180</span>
<span>3x + 2x−25 = 180</span>
5x - 25 = 180
5x = 180 +25
5x = 205
x =205/5
x =41
