Answer:
x=6
Step-by-step explanation:
Answer:
Step-by-step explanation:
You multiply the exponents to get:
Then you divide it by 
When dividing exponents, you subtract.
10 - - 2 = 12 so the exponent is 12.
That leaves us with:
Answer:
y=3x+10
Step-by-step explanation:
I dont think it is the right form but that Is an equation for it
<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
