x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
Since x by itself is the same as 1x, the expression can be re-written as 1x+2x Then, ignore the x's and simply add the numbers to obtain 1x+2x=3x 3x is your answer.
x
5
The answer is 4-1x
The expression x2 + 1x - 12 can be factored out as (x - 3)(x + 4)
First add coefficients: * 1x + 1x = 2x Second add the other values: * 4 + 5 = 9 Put it all together!: * 1x + 1x + 4 + 5 = 2x +9 * 2x + 9
2x+2=x+6 first subtract 2x. -2x -2x2=-1x+6 then subtract 6-6 -6-4=-1x finally divide by -1x=4 X equals four.
-1x=5nSteps:3x-4x=5n like terms3-4=-1 add x -1x-1x=5n not like termsanswer -1x=5n
1x - 14x = -13x. you cant subtract the four because it does not have an x on it so the answer would be -13x -4
2x2+1x-3=0 4+x-3=0 x+1+0 x=-1 is your final answer

x = 4 or x = -5
if is (x-6)-(1x-1) = -5 if id (x-6)-(1x+1) = -7
Let the number be represented by x. The product of a number decreased by 3 is (x-3), and increased by 4 is (x-3+4) = (x+1). According to the given condition, this product is equal to 8. Therefore, the polynomial equation representing this condition is: x+1 = 8.
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
