Please help me, I forget how to do these types of problems.
1- 6x+7=67
A 12
B10
C13
D6
2- x/4+2=-2
A 4
B-4
C12
D-16
- 6x+7=67
Subtract 7 from both sides.
Divide both sides by -6
- x/4+2=-2
Subtract 2 from both sides.
Multiply both sides by 4.
Sure, I'd be happy to help you with these problems step by step!
1. To solve the equation 6x + 7 = 67, we want to isolate the variable x on one side of the equation.
First, we'll get rid of the constant term 7 by subtracting 7 from both sides of the equation:
6x + 7 - 7 = 67 - 7
This simplifies to:
6x = 60
Next, we want to get rid of the coefficient 6 in front of the x. To do this, we divide both sides of the equation by 6:
6x/6 = 60/6
This simplifies to:
x = 10
Therefore, the value of x that satisfies the equation is 10. So the correct answer is B) 10.
2. To solve the equation x/4 + 2 = -2, we want to isolate the variable x on one side of the equation.
First, we'll subtract 2 from both sides of the equation:
x/4 + 2 - 2 = -2 - 2
This simplifies to:
x/4 = -4
Next, we want to get rid of the coefficient 1/4 in front of the x. To do this, we multiply both sides of the equation by 4:
4 * (x/4) = -4 * 4
This simplifies to:
x = -16
Therefore, the value of x that satisfies the equation is -16. So the correct answer is D) -16.
Remember to always perform the same operation on both sides of the equation to maintain balance, and keep simplifying until you isolate the variable on one side.
