Answer: 7 x + 6 = 6 x minus 3
Step-by-step explanation:
- 2 (x + 3) + 5 x = 3 (2 x minus 1)
- Now you distribute.
- 2(x) + 2(3) = 2x+6
- And 3(2x) minus 3(1) = 6x minus 3
- 2x+6+5x = 6x minus 3
- Then combine like terms
- 2x +5x=7x and there are no other like terms on either side of the equation.
- 7x+6= 6x minus 3

Answer:
part one:
6 3
22 1
30 0
part two:
0.50*s+4*a=15
Step-by-step explanation:
part one:
firstly:
6 individual songs cost 6*0.50= 3 dollars
she has 15 dollars so after downloading 6 individual songs that cost 3 dollars together
it means that she has only 15-3=12 dollars to download full albums
so 12/4=3 albums
because 4 dollar cost one album and with 12 dollars she can buy just 3 albums
secondary:
she downloaded 1 album
and one album cost 1*4=4 dollars
she has 15 dollars ,after buying 1 album
she has 15-4=11 dollars
so she can download 11/0.50=22 individual songs
so she can download 22 individual songs.
the last one:
she downloaded 30 individual songs
that all together cost 30*0.50=15 dollars
but she has 15 dollars at all so she cant buy any album because she spent all her money in individual songs.
because 15-15=0 money left
part two:equation
0.50*s+4*a=15
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*(2*x-6)-(10*x-6)=0
2x - 6 = 2 • (x - 3)
8 • (x - 3) - (10x - 6) = 0 -2x - 18 = -2 • (x + 9)
-2 • (x + 9) = 0 Solve : -2 = 0
<span>This equation has no solution.
</span>A a non-zero constant never equals zero.
Solving a Single Variable Equation :
Solve :
x+9 = 0 <span>
</span>Subtract 9 from both sides of the equation :<span>
</span> x = -9
Answer:
John paid $72
Step-by-step explanation:
To find the discount, we take the regular price and multiply it by the discount percentage
Discount = 90 * .2
= $18
The new price is the regular price minus the discount
New price = 90 -18
= $72
