Answer would be the bottom answer
Answer:
x = 10
Step-by-step explanation:
Okay, let's solve :)
So first we have to distribute on the left side(it doesn't matter which side FYI)
When we do, we have :
10x + 30 = -4(-5-2x)
Now we distribute on the right side! Remember, negative * negative = positive.
10x + 30 = 20 + 8x + 3x
Let's simplify on the right side to
10x + 30 = 20 + 11x
Now, let's subtract 10x on both sides to get
x + 20 = 30(i simply flipped the equation)
Subtract 20 on both sides to get!
x = 10!
Solution:
Since the graph passes through the given points, (7, 20) & (-2, 11) are the solutions of the given equation <em>y = x + ?</em>.
⇒<em>(x, y)</em> = (7, 20); (-2, 11)
Substituting the variables with (7, 20),
20 = 7 + <em>?</em>
20 - 7 = <em>?</em>
<em>?</em> = 13
Similarly,
11 = -2 + <em>?</em>
<em>?</em> = 13
∴ <em>y</em> = 13
