Sorry. I can't solve that because it is not an equation. An equation has an equals sign, and a solution is a set of assignments to the variables of the equation that would make it true.
For example: 2x - 3 = 5
That's an equation because it has an equals sign. There is only one real solution, x=4, because when x equals 4, the equation is true, and when x equals any other real number, then the equation is false.
2x + 3 = x - 4 2x + 7 = x x + 7 = 0 x = -7 2(-7) + 3 = -11 (-7) - 4 + -11
The above is not an inequality as stated.
(r3-3r2-5r-3)/(r-1)
7cos(x)=3sin(x) 7=3[sin(x)/cos(x)] 7=3tan(x) 7/3=tan(x) x=66.8, 246.8
2x+3=9x 3=9x-2x 3=7x x=3/7
Solve for x. 3x + 3 = x + 7 2x + 3 = 7 2x = 4 x = 2 Check it. 6 + 3 = 2 + 7 It checks.
-3+x=7. x=10
x=-2
x/3 - 7 = 2=> x/3 = 9 (add 7 to both sides) => x = 27 (multiply both sides by 3).
2x + 3 = x - 4 2x + 7 = x x + 7 = 0 x = -7 2(-7) + 3 = -11 (-7) - 4 + -11
3/7=x/63 189=7x 27=x
3/7=x/56 168=7x 24=x
4
x = 7 7-4/3 x 7 = 1/7 3/21 = 1/7
21 3,7 3 x 7 = 21
X + 3 = 10. X + 3 - 3 = 10 - 3 X = 7 Double check your solution. X + 3 = 10 7 + 3 = 10 10 = 10 So X + 3 = 10 when X = 7.
x - 7 - 9 = -3x - 16 = -3x = 13
