Answer:

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

Help please and explain how you did it
Harrizon [31]

1 yard = 3 feet

10 yards = 30 feet (multiply both sides by 10)

------------------

1 yard = 3 feet

2/3 yard = 2 feet (multiply both sides by 2/3)

-------------------

10 yards + 2/3 yard = 30 feet + 2 feet = 32 feet

<h3>The final answer is 32 feet</h3>

What is the x in 120(2x-2)=240
coldgirl [10]

Answer:

X=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

120(2x−2)=240

(120)(2x)+(120)(−2)=240(Distribute)

240x+−240=240

240x−240=240

Step 2: Add 240 to both sides.

240x−240+240=240+240

240x=480

Step 3: Divide both sides by 240.

240x /240 = 480 /240

x=2
