Answer:
<h2>Add 24 and 40</h2>
Step-by-step explanation:
3(8 - 2x) + 40 = 34 <em>use the distributive property a(b + c) = ab+ ac</em>
3(8) + 3(-2x) + 40 = 34
24 - 6x + 40 = 34 <em>combine like terms</em>
-6x + (24 + 40) = 34 <em>Answer: Add 24 and 40</em>
-6x + 64 = 34 <em>subtract 64 from both sides</em>
-6x = -30 <em>divide both sides by (-6)</em>
x = 5
<h2>x = 1/4</h2><h2>y = -2</h2><h2>______________</h2>
<h2>Known : </h2>
y = -8x
4x - y = 3
<h2>Asked: </h2>
Use the substitution method to solve the system of equations ?
<h2>Answered:</h2>
<h3>Substitution y</h3>
4x - y = 3
4x - (-8x) = 3
4x + 8x = 3
12x = 3
x = 3/12
x = 1/4
<h3>
Substitution x</h3>
4x - y = 3
4(1/4) - y = 3
4/4 - y = 3
1 - y = 3
-y = 3 - 1
-y = 2
y = -2
Depends on where you are in the math book but this would be the most simple way.
