Which equation can be used to solve for x?
30x – 5 = 67
7x + 18 = 67
30x + 5 = 67
7x + 28 = 67
To solve for ( x ), we can use any equation that contains ( x ) and equates to a number. Let’s analyze the provided equations:
1. 30x – 5 = 67: This equation can be solved for ( x ).
2. 7x + 18 = 67: This equation can also be solved for ( x ).
3. 30x + 5 = 67: This equation can be solved as well.
4. 7x + 28 = 67: This equation can also be solved for ( x ).
However, if you are looking for a specific equation to solve for ( x ), all of these equations can work. You can choose any of them to find the value of ( x ).
For an example, let’s solve 7x + 18 = 67:
1. Subtract 18 from both sides:
( 7x = 67 – 18 )
( 7x = 49 )
2. Divide both sides by 7:
( x = frac{49}{7} )
( x = 7 )
So, you can choose any of these equations to solve for ( x ). If you need help with a specific equation, feel free to ask!
