Use the substitution method to solve the following system of equations.

Paraphin [41]

(4x - y = 3) * 9
36x - 9y = 27

7x - 9y = -2

29x = 29
x = 1

y = 4*1 - 3
y = 1

3(a - 1) + 2a = a + 1

tresset_1 [31]

Answer:

a = 1

Step-by-step explanation:

Step 1: Write equation

3(a - 1) + 2a = a + 1

Step 2: Solve for <em>a</em>

<u>Distribute 3:</u> 3a - 3 + 2a = a + 1

<u>Combine like terms:</u> 5a - 3 = a + 1

<u>Subtract a on both sides:</u> 4a - 3 = 1

<u>Add 3 on both sides:</u> 4a = 4

<u>Divide both sides by 4:</u> a = 1

1. $\frac{x^3}{x^8}=x^{-5}$

2. $\frac{6x}{2x^8} = 3x^{-7}$

3. $\frac{28x^6}{21x^2} = \frac{4}{3}x^4$

Step-by-step explanation:

<u>1. x^3/x^8</u>

Given fraction is:

$\frac{x^3}{x^8}$

When the bases are same in both numerator and denominator then the exponents can be added

i.e.

$\frac{x^a}{x^b} = x^{a-b}$

So,

$\frac{x^3}{x^8} = x^{3-8} = x^{-5}$

<u>Part b:</u>

$\frac{6x}{2x^8}\\= \frac{3.2.x}{2.x^8}\\=\frac{3x}{x^8}\\=3x{1-8}\\=3x^{-7}$

<u>Part c:</u>

Given

$\frac{28x^6}{21x^2}\\= \frac{7.4.x^6}{7.3.x^2}\\=\frac{4}{3} x^{6-2}\\=\frac{4}{3}x^4$
