9x + 91 is already simplified because there is nothing that is on the other side of the "equals" sign.
x+5+3x-7+9x+3-4x Collect like terms: 9x+1
You can just add them together. The answer is 9x.
12x + 6=9x + 27 12x-9x + 6=9x - 9x + 27 subtract 9x from both sides. 3x + 6 = 27 simplify 3x + 6 - 6=27 - 6 subtract 6 from both sides. 3x=21 simplify 3x/3=21/3 divide both sides by 3 x=7 simplify 12(7) + 6=>84+6=>90 9(7) + 27=>63+27=>90 It checks out!
That will depend on the plus or minus value of 4y in order to simplify the given expression

It is 14x+4 simplified
x+5+3x-7+9x+3-4x Collect like terms: 9x+1
You can just add them together. The answer is 9x.
9x2+9x-12 All I can do is simplify this. I can't solve it unless turn this expression into an equation.
minus 4 plus 9 = 5, so 5x
i thinking this answer should be -20
Right, 3x-4x+9x-x1. 3x - x = 2x2. 9x-4x = 5x- 2x +5x = 7x
In this case you just add them together to make 9x.
12x + 6=9x + 27 12x-9x + 6=9x - 9x + 27 subtract 9x from both sides. 3x + 6 = 27 simplify 3x + 6 - 6=27 - 6 subtract 6 from both sides. 3x=21 simplify 3x/3=21/3 divide both sides by 3 x=7 simplify 12(7) + 6=>84+6=>90 9(7) + 27=>63+27=>90 It checks out!
5*2+9x-2=0 so, going by BODMAS rule 10+9x-2=0 9x=-10+2 9x=-8 x=-8/9 I think!!
14 + 2x + 9x - 6 - 11x 14 - 6 + 2x + 9x - 11x The x values cancel themselves out, leaving just the number value The answer is therefore 8.
