Answer:

y = 7

Step-by-step explanation:

6y+3=45   (subtract 3 from both sides)

6y = 45 - 3

6y = 42 (divide both sides by 6)

y = 42/6

y = 7

Answer:

y=7

Step-by-step explanation:

To solve the equation, we want to find out what <em>y</em> is. In order to do this, we have to get <em>y</em> by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

6y+3=45

3 is being added to 6y. The opposite of addition is subtraction. Subtract 3 from both sides.

6y+3-3=45-3

6y=45-3

6y=42

6 and y are being multiplied (6*y=6y). The opposite of multiplication is division. Divide both sides by 6.

6y/6=42/6

y=42/6

y=7

Let's check our solution. Plug 7 in for y in the original equation.

6y+3=45

y=7

6(7)+3=45

42+3=45

45=45

Both sides of the equation are the same, so we know our solution is correct.

Solve -2 = 5p + 3p -8 – 6p
Shalnov [3]

Answer:

P=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2=5p+3p−8−6p

−2=5p+3p+−8+−6p

−2=(5p+3p+−6p)+(−8)(Combine Like Terms)

−2=2p+−8

−2=2p−8

Step 2: Flip the equation.

2p−8=−2

Step 3: Add 8 to both sides.

2p−8+8=−2+8

2p=6

Step 4: Divide both sides by 2.

2p2=62

p=3

regular price=$429

429-150.15=278.85

35% discount amount: $278.85

278.85(0.05)=13.94

278.85+13.94=292.79
