Answer:

x = -12 not 12 as in previous response

Step-by-step explanation:

(3x-2)/4 + 5 = (x+3)/2 put terms on left and constants on right

(3x-2)/4 - (x+3)/2 = -5

multiply all terms by 4

(3x-2) - 2(x+3) = -20 now simplify by distributing -2 in second term

3x - 2 - 2x - 6 = -20 combine like terms

x -8 = -20 now add 8 to both sides

x = -12

John spent $19.00 at the tuck shop. He bought 2 chocolate bars and 3 packets of
laila [671]

Answer:

It will cost Jane $21.00

Step-by-step explanation:

As, cost of 1 chocolate = x

The cost of 1 packet of chips = $3 + x

So no. Of 2 chocolate bars = x + x = 2x

And no. Of packet of chips = ($3+x) + ($3+x) + ($3+x) = 3(3+x) = 9+3x

So now = cost Of chocolate + cost of chips = $19

So = 2x + 9+3x = 9 + 5x

So 9 + 5x = $19

So 5x = $19 - 9 = $10

So 5x =10

x = 10/5

x = 2

So cost of 2 chocolate = 2x = 2($2) = $4

And 3 chip packet = 9+3x = 9+3($2) = 9+6 =$15

So now total = $4 + $15 = $19

Now for John = 2 chocolates and 3 packets of chips = $19

Now for Jane she has 3 chocolates and 3 packets of chips, so she has one more chocolate amd now we know that 1 chocolate = $2

So we will just add one more chocolate

So Jane will pay = $ 19 + $2 = $21

So it will cost Jane = $21:00

Classify the equation as a conditional equation, an identity, or a contradiction.
Goryan [66]

Since the equation is a true one, then it is an identity.

<h3>How to illustrate the information?</h3>

It should be noted that the information given is represented as 9(a−4)+3(2a+5)=7(3a−4)−6a+7.

After using the distributive law, the value that will be gotten will be:

15a - 21 = 15a - 21.

Therefore since the equation is a true one, then it is an identity.
