Solving Linear Equations:
x
_ - 3 = 5
7
I know you have to add three to each side, but after that im not sure what to do,, please help!
x/7 = 8
Multiply both sides by 7.
x = 56
I don't understand how x/7 is 8 because how do you know what x is ???
(x/7) - 3 = 5
Add 3 to both sides.
x/7 = 8
Multiply both sides by 7.
(x/7) * 7 = 8 * 7
x = 56
Proof:
(56/7) - 3 = 5
8 - 3 = 5
To solve the linear equation, you need to isolate the variable x. Here's how you can solve it step by step:
1. Start with the equation:
(x/7) - 3 = 5
2. To get rid of the -3 on the left side, you can add 3 to both sides of the equation:
(x/7) - 3 + 3 = 5 + 3
(x/7) = 8
3. Now, you want to isolate x. To do that, multiply both sides of the equation by 7 (the denominator of x/7):
7 * (x/7) = 8 * 7
x = 56
Therefore, the solution to the equation is x = 56.
