SOLVING+LINEAR+EQUATIONS


 * FORMULAS

Open Sentence **- an equation or inequality that contains a variable. Any value o fthe variable that makes the open sentence true is called a solution.

x+5= 15 x= 10


 * Remember to perform order of operations before solving the open sentence!!

3( 2x+5) = -7 (x+9) 6x+15 = -7x - 63
 * 1) Distribute through the parentheses

2. Isolate the variable on one side by moving all constants to one side and all coefficients to the other

13x = -78

3. Isolate the variable completely by dividing the constant by the coeffient

x = -78/ 13

4. x= -6

~If there is a fraction in the equation multiply all numbers through to rid of fraction before solving the equation.

3/4x + 1/2 = -2 3x + 2 = -8
