Answer:
2x = 10
Step-by-step explanation:
7 + 3x = 22
-7 -7
Subtract 7 from both sides (you are trying to get the variable alone, and to do that, you have to get every other number to 0. <em>7 - 7 = 0</em>. BUT, whatever you do, you have to do to both sides.)
3x = 15
/3 /3
Divide both sides by three to get the variable alone.
x = 5
Now, plug in the value of x to the second equation and solve.
2(5) = ? --> 10

So multiplying two rationals is the same as multiplying two such as fraction as when you multiplying two rational numbers produces another rational number.
If r = 1/6 and 1/6 is next to 12, it's multiplication. so that's 12 x 1/6.
12 x 1/6 = 2 i believe.
The sum: is the answer to an addition problem. "And" usually represents the plus sign. "times" is used to signify multiplication.
So, the sum "s" of 3 and the quatity 8 times p is equal to:
3+8p= s
