Can you please give me a example of a - and + multi step equation
Sure, I can provide an example of a multi-step equation that involves both subtraction (-) and addition (+).
Let's say we have the equation:
3x - 7 + 5 = 15
To solve this equation, we need to follow a series of steps:
Step 1: Combine like terms
First, we combine the -7 and +5 to get -2:
3x - 2 = 15
Step 2: Isolate the variable
Next, we need to isolate the variable (in this case, x) by getting rid of the -2 on the left side of the equation. To do this, we need to add 2 to both sides of the equation:
3x - 2 + 2 = 15 + 2
Which simplifies to:
3x = 17
Step 3: Solve for the variable
Finally, to solve for x, we divide both sides of the equation by 3:
(3x)/3 = 17/3
This gives us:
x = 17/3, which is the solution to the equation.
So the solution to the given multi-step equation, 3x - 7 + 5 = 15, is x = 17/3.
