@bot do this but in different equations Equation 1: 3x + 5 = 20 Equation 2: 2x - 8 = 10 Open Equation: 2x + 7 = 15 Solve for x: 2x = 15 - 7 2x = 8 x = 8 / 2 x = 4
Equation 1: 3x + 5 = 20
3x = 20 - 5
3x = 15
x = 15 / 3
x = 5
Equation 2: 2x - 8 = 10
2x = 10 + 8
2x = 18
x = 18 / 2
x = 9
Open Equation: 2x + 7 = 15
2x = 15 - 7
2x = 8
x = 8 / 2
x = 4
To solve the open equation, 2x + 7 = 15, for x, you'll need to follow these steps:
Step 1: Subtract 7 from both sides of the equation to isolate the term with the variable on one side:
2x + 7 - 7 = 15 - 7
This simplifies to:
2x = 8
Step 2: Divide both sides of the equation by 2 to solve for x:
2x / 2 = 8 / 2
This simplifies to:
x = 4
Therefore, the value of x in the equation 2x + 7 = 15 is 4.
Sure! Here's how you can solve the equations step-by-step:
Equation 1: 3x + 5 = 20
Step 1: Start by subtracting 5 from both sides of the equation to isolate the variable.
3x + 5 - 5 = 20 - 5
3x = 15
Step 2: Divide both sides of the equation by 3 to solve for x.
3x/3 = 15/3
x = 5
Therefore, x = 5 is the solution for Equation 1.
Equation 2: 2x - 8 = 10
Step 1: Start by adding 8 to both sides to isolate the variable.
2x - 8 + 8 = 10 + 8
2x = 18
Step 2: Divide both sides of the equation by 2 to solve for x.
2x/2 = 18/2
x = 9
Therefore, x = 9 is the solution for Equation 2.
Open Equation: 2x + 7 = 15
Step 1: Start by subtracting 7 from both sides to isolate the variable.
2x + 7 - 7 = 15 - 7
2x = 8
Step 2: Divide both sides of the equation by 2 to solve for x.
2x/2 = 8/2
x = 4
Therefore, x = 4 is the solution for the open equation.
