Answer:
Step-by-step explanation:
2(3x−5)+4x−10=4x+2(x+6)
Step 1: Simplify both sides of the equation.
2(3x−5)+4x−10=4x+2(x+6)
(2)(3x)+(2)(−5)+4x+−10=4x+(2)(x)+(2)(6)(Distribute)
6x+−10+4x+−10=4x+2x+12
(6x+4x)+(−10+−10)=(4x+2x)+(12)(Combine Like Terms)
10x+−20=6x+12
10x−20=6x+12
Step 2: Subtract 6x from both sides.
10x−20−6x=6x+12−6x
4x−20=12
Step 3: Add 20 to both sides.
4x−20+20=12+20
4x=32
Step 4: Divide both sides by 4.
4x/4 =32/4
x=8
If a single board measures 1/12 of a meter then it would take 12 boards to make a meter. Since, the stack is 2 meters high. You would multiply 12 and 2 to get 24. There is 24 boards in the stack.
