<h2>Answer:</h2>

-3.8x + 7 and c = -75/14 and/or c = -5.35714

<h3 /><h2>Step-by-step explanation:</h2>

<em>First equation: </em>

1.2x + 7 - 5x =

Step 1 - Group like terms:

1.2 - 5x + 7

Step 2 - Add simliar elements:

1.2 x - 5x = -3.8x =

3.8x + 7

Answer: -3.8x + 7

<em>Second equation:</em>

2.2c - 3 = 2(6 - c) + 7c =

Step 1 - Multiply both sides by 10:

2.2c ⋅ 10-3 ⋅ 10 = 2(6 - c) ⋅ 10 + 7c ⋅ 10

Step 2 - Refine:

22c - 30 = 20(6-c) + 70c =

<em> - Expand 20(6-c): 120 - 20c</em>

22c - 30 = 120 - 20c + 70c

Step 3 - Add similar elements:

-20c + 70c = 50c =

22c - 30 = 120 + 50c

Step 4 - Add 30 to both sides:

22c - 30 + 30 = 120 + 50c + 30

Step 5 - Simplify:

22c = 50c + 150

Step 6 - Subtract 50c from both sides:

22c - 50c = 50c + 150 - 50c

Step 7 - Simplify:

-28c = 150

Step 8 - Divide both sides by -28:

-28c/-28 = 150/-28

Step 9 - Simplify:

c = -75/14

Answer:

Fraction form: c = -75/14

Decimal form: c = -5.35714

<em>Hey! Your question wasn't quite clear, so the most I could do was simplify both equations in a way you can hopefully understand. If these aren't the answers you were looking for, please elaborate on what I was supposed to answer!</em>

A bride and groom both invited guests to their wedding. The bride invited twice as many women as the groom did, and the groom in
n200080 [17]

Answer:

option 1) 50

Step-by-step explanation:

Let m and w denote the men and women respectively.

From the question, if the groom invited w number of women, then bride invited 2w number of women.

Also, if the bride invited m number of men,then the groom invited 2m.

Hence we can write the following maths equation:

w+2m=105.........1

2w+m=135.........2

We multiply eqn(1) by 2 to get eqn(3)

This implies that,

2w+4m=210.......3

We then subtract eqn (2) from eqn(3) to obtain;

3m=75

we divide through by 3

\implies \frac{3m}{3} = 75

\implies m= 25

Substituting the value of m into eqn (1)

to find the value for w

\implies w + 50 = 105

subtracting 50 from both sides.

\implies w + 50  - 50= 105 - 50

\implies w+2(25)=105

\implies w= 55

So we can say the :

bride invited 25 men and 110 women,

groom invited 50 men and 55 women.
