With all solve for x, j, p, show work 1. 8p - 3=13 2. 8j - 5 + j =67 3. 3(2x - 5) = 4x+33 4. c= b - bx

1. 8p-3=13

+3

8p=16      /8

p=2

2. 8j -5 +j=67

==            9j=72    /9

j=8

3.   3(2x-5)=4x+33   <--- =expand ()

6x-15=4x+33      ---> 2x=48

x=24

4. c=b-bx

get just x's on one side

c-b=bx

divide by b---> (c-b)/b=x

1. p = 2

2. j = 8

3. x = 24

Step-by-step explanation:

In order to solve any of these, simply follow the order of operations of solving. Below is each example explained for you.

1.

8p - 3 = 13 > Add 3 to both sides

8p = 16 > Divide both sides by 8.

p = 2

2.

8j - 5 + j = 67 > Combine like terms

9j - 5 = 67 > Add 5 to both sides

9j = 72 > Divide both sides by 9

j = 8

3.

3(2x - 5) = 4x + 33 > Distribute the 3

6x - 15 = 4x + 33 > Subtract 4x from both sides

2x - 15 = 33 > Add 15 to both sides

2x = 48 > Divide both sides by 2

x = 24

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

factor trees are nice.
