12x + 131 = 189 + 3x 12x - 3x + 131 - 189 = 0 9x - 58 = 0 9x = 58 x = 6,44444
5x-3x+x+8 = 2x+1+x+x 3x+8 = 4x+1 3x-4x = 1-8 -x = -7 x=7 Hope that helps.
X2+3x+x+3=x(x+1)+3(x+1)=(x+3)(x+1)
3x2 + x = x*(3x + 1)
1 + 3x - x = x - 4 + 2x 1 + 4 = x + 2x - 3x + x 5 = x
12x + 131 = 189 + 3x 12x - 3x + 131 - 189 = 0 9x - 58 = 0 9x = 58 x = 6,44444
5x-3x+x+8 = 2x+1+x+x 3x+8 = 4x+1 3x-4x = 1-8 -x = -7 x=7 Hope that helps.
3X = X + 58 subtract X from both sides 2X = 58 divide both sides by 2 X = 29 check 3(29) = 29 + 58 87 = 87 checks
X2+3x+x+3=x(x+1)+3(x+1)=(x+3)(x+1)
3x2 + x = x*(3x + 1)
1 + 3x - x = x - 4 + 2x 1 + 4 = x + 2x - 3x + x 5 = x
yes cause like when u do x plus x plus x , its like 1 plus 1 plus 1 so its 3x just like 3
x + 2 = 3x-1 -2x = -3x = 1,5
4x=3x+1 => (4x-3x)=1 => x=1 therefore the value of x is 1.
x-2=3x+1 x=3x+1+2 x-3x=3 -2x=3 x=-3/2
2x2 + 3x + 1 = (x + 1)(2x + 1)
If 3x + 5x = -8, what is x + 1? 3x + 5x = -8 8x = -8 x = -1 x + 1 = -1 + 1 = 0
