9. Solve the equation.
x + 4 = 3(3x - 4)
A 9
4
B 1
C 2
Lounge
D 7
4

x=2

Step-by-step explanation:

x + 4 = 3(3x - 4)

Distribute

x+4 = 9x -12

Subtract x from each side

x+4 -x = 9x-x-12

4 = 8x-12

Add 12 to each side

4+12 = 8x-12+12

16 = 8x

Divide by 8

16/8 = 8x/8

2 =x

x = 2

Step-by-step explanation:

x + 4 = 3(3x - 4)

Expand the brackets.

x + 4 = 9x - 12

Add -x and 12 on both sides.

4 + 12 = 9x - x

16 = 8x

Divide 8 into both sides.

16/8 = x

2 = x

Switch sides.

x = 2

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
