Answer:
x = 7.
Explanation:
So any number and variable combination like 8x or 2y means that you multiple that number by the value of the variable. In this case we know that y = 4 so we multiply the 2 by 4 to get 8. Now we have the equation:
8x - 8 = 48
In order to solve for x, we must get it by itself, which means moving every known number and variable over to the opposite side of the equal sign. You start this by moving over the number that is the furthest away from the variable you are trying to solve for, in this case, x. You would start by moving over the 8. In order to move it over, you must perform the opposite function, so in this case, you would add 8 to both sides of the equation giving you:
8x = 56
Like stated before any number right next to a variable, just means they get multiplied together, so the opposite of multiplication is division so we would divide the 56 by the 8 giving us
x = 7
