Here is a two-step equation example with steps to solve it:
2x + 3 = 11
Subtract 3 from both sides using the subtraction property of equality:
2x + 3 - 3 = 11 - 3
2x = 8
Divide both sides by 2 using the division property of equality:
2x/2 = 8/2
x = 4
To solve a two-step equation:
1) Use addition or subtraction to isolate the variable term on one side of the equation.
2) Use multiplication or division to solve for the variable.
By applying the properties of equality, this allows you to transform the original equation into an equivalent equation where the variable term is alone
1. To solve linear systems by multiplying, arrange the equations so that like terms are in columns. Multiply one or both equations by a number to obtain opposite coefficients for one variable.
2. Add or subtract the equations to eliminate one variable. Solve for the remaining variable and substitute back into the original equations.
3. Check the solution by substituting the values back into the original equations.
The document provides examples and practice problems for solving polynomial equations by factoring polynomials to find their roots using the zero-product property.
