Question:

Find an expression for x with the following: y(x-1)=z

Jamie D.

This is an equation and has multiple unknowns. However, we don't need to be intimated by it, because in this case, we are not getting a specific number for x, but an expression containing y and z. First, we multiply the element in the parenthesis by y, which gives xy-y=z. Because we want to solve for x, then we add a y to both sides so that the left side is only left with the x term, then we get xy=z+y. Finally, we will divide both sides by y, which gives x=(z+y)/y

Question:

Solve for the x in this equation: 3x+4 = 25

Jamie D.

This question asks us to solve for x, which is also called a variable or unknown. First, we can subtract 4 from both sides so that the left side is then only left with a factor, in this case, 3 multiple by the unknown. Then we'll have 3x = 21. The next step is to divide both sides by 3 so that the left side is only left with x and the right side is the answer, in this case, x=7.
