Question

1. 4m+3=13-m 2. 5p+5=4+4p 3. 8+6x=8+8x+7+3

Answer 1

1. m= 13/3 or m= 4 1/3

2.p=-1

3. x=-5

Explanation:

1. 4m+3=13-m (given) 3m=13 (combine like terms) m=13/3 (divide both sides by 3)

2. 5p+5=4+4p (given) p=-1 (combine like terms, this is your answer)

3. 8+6x=8+8x+7+3 (given) -10=2x (combine like terms) -5=x (divide by 2)

Answer 2

1) m= 2, 2) p= -1, 3) x= -5

Explanation:

Number 1:

4m+3=13-m

Add m to both sides

5m+3=13

Subtract 3 from both sides

5m = 10

Divide by 5 on both sides

m=2

Number 2

5p+5=4+4p

Subtract 4p on both sides

p+5=4

Subtract 5 from both sides

p=-1

Number 3

8+6x=8+8x+7+3

Combine like-terms

8+6x=8x+18

Subtract 6x from both sides

8=2x+18

Subtract 18 from both sides

-10=2x

Divide both sides by 2

x=-5
