Lets say that the equation is: 2+3x+2x=22
- 2+5x=22 Combine Like Terms.
- 2-2+5x=22-2 Subtract 2 from each side.
- 5x=20 Simplify.
- 5x/5=20/5 Divide 5 on each side.
- x=4 Simplify.
Check...
- 2+3x+2x=22 x=4
- 2+3(4)+2(4)=22 Substitute x for 4.
- 2+12+8=22 Multiply and Divide first from left to right.
- 14+8=22 Add and Subtract from left to right.
- 22=22
Should you have an equation with higher order (like x2) then different methods, like factoring or the quadratic formula will apply.
Eh?
