Solving Linear Equations

Solve for x:

4x+14+4x=38

• x=3

• x=1

• x=99

solve for n:

-12=10n-40n+3

• n=3/4 or .75

• n=1/2 or .5

• n=1

Solve for b:

b+8-10=6

• b=10

• b=8

• B=16

What is the first step?

-14=7w+2w+8

• Combine Like Terms

• Isolate the variable

6x+7x-8=18

• x=8

• x=2

• x=-2

What is the first step in this equation?

17n-23n+11.5n=44

• combine like terms: 17n-23n+11.5n to equal 5.5n=44

• subtract 11.5 from both sides

• add 23 to both sides

what does this equation look like after we combine like terms AND THEN subtract the constant (numbers not next to the letter)?

-12t+10+32=78

• -12t+10=78

• -12t=36

• 12t+42=78

• x=8
• x=2
• x=4
• x=-2
