HOW DO U SOLVE TWO STEP EQUATIONS????
Two ways.
1. Multiply each equation by a number such that one of the variables will add to zero, thus eliminating that variable. Then solve for the other variable.
2. Solve one equation for either variable in terms of the other variable, then substitute this value into the second equation and solve for the remaining variable.
To solve two-step equations, you need to follow a few simple steps:
Step 1: Remove any addition or subtraction first. To do this, use the inverse operation to isolate the variable. If there is an addition, you subtract that number from both sides of the equation. If there is a subtraction, you add that number to both sides of the equation.
Step 2: Remove any multiplication or division. Again, use the inverse operation to isolate the variable. If there is a multiplication, you divide both sides of the equation by that number. If there is a division, you multiply both sides of the equation by that number.
Here's an example to help illustrate the process:
Let's solve the equation: 3x + 5 = 17
Step 1: Remove the addition by subtracting 5 from both sides:
3x + 5 - 5 = 17 - 5
3x = 12
Step 2: Remove the multiplication by dividing both sides by 3:
(3x) / 3 = 12 / 3
x = 4
Therefore, the solution to the equation 3x + 5 = 17 is x = 4.
