Linear Equations 1.1 & 1.3 A linear equation: 1.Get rid of functions 2. Simplify like terms on each side 3. Isolate the variable 4. Solve 1. 2x-5=7+6x ● Move the 6x to the left side ● Add the 5 to the right side That gives you -4x=12 ● Divide -4 by -4x ● Divide -4 by 12 That gives you x=-3 as your final answer 2. 2(x-5)+3x=x+6 ● Distribute the 2 to the x and -5 ● Combine 2x and 3x ● Add 10 to the right side ● Subtract 1 to the left side ● Divide 4 by 4x ● Divide 4 by 16 That gives you x=4 as your final answer 3. 4x+8+x=3-10+5x ● Add that understood 1 to the x ● Combine 4x and 1x ● Combine 3 and -10 ● Subtract 8 to the right side ● Subtract 5x to the left side ● The 5x on the left cancels
