Use the distributive property, ac + bc = (a+b)c; in this case, just add the numbers and place an "x" at the end. This works if the variable or variables (in this case, "x") is the same for both parts.
4x+2=2x-102x=-12 x=-6
108x2-102x+24 Simplified by dividing all terms by 6: 18x2-17x+4 When factorised: (9x-4)(2x-1) With a question like this using the quadratic equation formula will help.

3a * * * * * Actually, it is 4a.
If you simplify the equation (s+t+s) the answer is 2s+t
x -3x + 4 = 3 - 9-2x + 4 = -6-2x = -102x = 10x = 5
When you simplify 49 plus 37 (49+37), the result is 86.
