2x+7=3(x-4) type out your steps

x=19

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x+7=3(x−4)

2x+7=3(x−4)

2x+7=(3)(x)+(3)(−4)(Distribute)

2x+7=3x+−12

2x+7=3x−12

Step 2: Subtract 3x from both sides.

2x+7−3x=3x−12−3x

−x+7=−12

Step 3: Subtract 7 from both sides.

−x+7−7=−12−7

−x=−19

x=19

16.

Step-by-step explanation:

The top side of the first parallelogram is 42 and the second one is 24. The parallelograms are proportional. If you divide 42 by 24, you get 1.75. Then if you flip the equation around, 42 times 1.75 is 24. Now you found a way to find the missing side. You do the same thing to 28. So 28 times 1.75 is 16, which us your answer. Sorry if this doesn't make sense, I can't really explain it well lol.
