Algebra is using variables such as x to solve a problem. One example is x+3=8 in which x equals 5.
You use algebra and solve the system(s) of equations using techniques such as elimination or substitution.
x + 4 = 6 x = 6 - 4 x = 2
To solve the equation ( r(x) = 0 ), you need to find the values of ( x ) for which the function ( r(x) ) equals zero. This typically involves setting the function equal to zero and solving for ( x ) using algebraic methods, factoring, or numerical techniques if necessary. The solutions are the points where the graph of the function intersects the x-axis.
Using algebra to solve this problem (12 + .25x = 30), the answer (x) is 72.
