Expression: x+10+5x Solve: x+5x=6x Answer: 6x+10
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
3x + 2x = 5x
5x+3+x=24 6x+3=24 6x=21 x=3.5
x = -8
172=x
(x-3)(x-2)
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
If you mean: 3+5x+7 = 70 then the value of x is 12
Then x = 6 Therefore; 5x + 3 = 33 First you have to solve the value of X: 8X + 5X + 2X +4X = 114; OR 19x = 114. When you divide both sides of the equation by 19 to solve for X, you find that X = 6. Ergo, 5X + 3 = 30 + 3 = 33; hence, 5X + 3 = 33.
f(x) = x2 + 5x + 1 The roots of this equation are x = -0.2087 and x = -4.7913 (approx).
