10 + 2(x - 1) + 7 x 3x + 1 =10 + 2x - 2 + (7 x 3x) + 1 =10 + 2x - 2 + 21x + 1 =2x + 21x + 10 - 2 + 1 =23x + 9
x^2 + 3x - 2; -x^2 - 3x + 2andx - 1; 1 - x
x + 3x - 10 = 5 - 4 4x - 10 = 1 4x = 1 + 10 x = 11/4
It is equivalent to: 3x+6+5 = 3x+11
3x + 2 = -10 3x = -12 x = -4
3x + 6x +1 = 10 9x = 10 - 1 9x = 9 x = 1
(x + 1)(3x + 10)
3+3x+7x=13 3x+7x=10 10x=10 x=1
(2, -1)
3x + 4y + 10 + 12x + y + 1 First, combine like factors: 3x +12x + 4y + y +10 + 1 Add them (or subtract) as necessary: 15x + 5y + 11
x= -3 -3(-3) +1=10 also: -3X-3+1=10
10 + 2(x - 1) + 7 x 3x + 1 =10 + 2x - 2 + (7 x 3x) + 1 =10 + 2x - 2 + 21x + 1 =2x + 21x + 10 - 2 + 1 =23x + 9
x^2 + 3x - 2; -x^2 - 3x + 2andx - 1; 1 - x
5x+10-5y-3x+1=0 <--You start with this. Then move the 10 and 1 to the other side by subtracting them. 5x-5y-3x=-11<--Next combine the x's 2x-3y=-11<--This is the simplified answer.
3x + x + 10 + x = 5x + 10
x=-3
If: x+7-4x+1 = -10 Then: 8-3x = -10 And: -3x = -10-8 => -3x = -18 So: x = -18/-3 => x = 6
