Hello russell6333!
Solve for x.
- 144 = 12x
- 45 = 4x - 27
- 2x - 2 = 14
- 12x = 44 - 10x

<h3><u>NOTE </u><u>:</u><u>-</u></h3>- To solve questions of these sorts, bring all the terms to one side & simplify it leaving x alone in the other side of the equation (other side of the equal to sign). After simplification you'll get the value of x.
- Remember that the signs & operations will change when you bring a term to the other side of the equation.
- So, addition will become subtraction, subtraction will become addition, multiplication will become division & division will become multiplication.

let the two numbers be x and y
From the first sentence,
xy=24
x+y=10
Then make y in equation 2 the subject of the formular and substitute in equation 1
x+y=10
y=10-x
substituting in equation 2
x(10-x)=24
open the bracket
10x-x^2=24
=-x^2+10x=24
Transfer the constant to the left hand side
=-x^2+10x-24=0
Then factorise completely
