Alright so, in order to solve an equation, you must have the unknown by itself.
So, we first subtract 7 from both sides and get a new equation.
-6x = 72
Now we divide by -6 so that x is by itself.
x = -12.
Now, -12 is a *possible* solution to the equation. The way to find out is to check. Checking the answer means "plugging in" the number into the equation, and seeing if it solves. so.
-6 * -12 + 7 = 79
72 + 7 = 79
79 = 79
So, since the answer checked out, -12 is a solution to the equation.
Hope this helps.

No, this is not true every time. It depends on the conditions given.
For example-
Suppose we have a Box A with dimensions 10 x 10 x 1 and Box B with dimensions 5 x 5 x 5.
Box B has a surface area = 2(25+25+25) = 150 and a volume of 5*5*5= 125 cubic units
Box A has a larger surface area = 2(100+10+10) = 240 and a smaller volume = 10*10*1 = 100 cubic units
Similarly take an example of sphere.
Lets suppose the radius of the sphere is 2 cm
So, SA is 4πr² = 4*3.14*2*2 = 50.24 cm²
Volume of the sphere is = 4πr³ /3 = 33.50 cm³
Here also the SA is greater.
Answer:
Step-by-step explanation:
Solve 3y + 10.5 = 6.5 + 2.5y.
Add -2.5y to both sides so that the variable remains on one side only. Now isolate the variable by subtracting 10.5 from both sides. Multiply both sides by 10 so that 0.5y becomes 5y, then divide by 5. Check your solution by substituting -8 in for y in the original equation.
