substitute the value of x which is 3 :10/ (2-x)+4 = -10+4= -6
It is an algebraic expression.
5x - 4x = 13 - 3 ie x = 10
If: x+7-4x+1 = -10 Then: 8-3x = -10 And: -3x = -10-8 => -3x = -18 So: x = -18/-3 => x = 6
x/2 = x/5 + 1 5x = 2x + 10 3x = 10 x = 3 1/3
x + 3 + 10 = x + 13
10 + 3(x + 2) = 31
It is: (-10)+(-3)+4 = -9
If x = 3, then x + 10 would be 3 + 10, which is 13.
Add the following: 10 x 10 plus 2 x 10 plus 3 x 10 plus 2 x 3 That makes it easier to do it without a pen or calculator.
3+10 = 13
3 + √x = 10 √ x = 10 - 3 √ x = 7 x = 7² x = 49
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^2 + 13x + 30 = 0 x^2 + 10x + 3x + 30 = 0 x(x + 10) + 3(x + 10) = 0 (x + 3)(x + 10) = 0 x = -3 or x = -10
1 plus 1 x 2 plus 3 x 42 plus 10 x 5 = 1 + 2 + 126 + 50 = 179
If: x/3 + 10 = 15 Then: x = 15
If (x+7) > 10, then x > 3. If (x+7) < 10, then x < 3.
