Given LBRW and = 15 and = 3x - 9, what is the value of x? 8
Do you mean "what is the value of x when 3x - 2x = 15?" in that case, the value of x is 15
If you mean: x^2+15-3x then its value is 19 when x equals 4

If: 3x = 15 Then: x = 5

Given a value of x, find the value for -3x + 2
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
negative 15

Equation of given line: 3x + y = 15 or y = -3x + 15 Slope of given line = coefficient of x = -3 Slope of perperndicular = -1/(slope of given line) = -1 / (-3) = 1/3
3x + 5 = 4x - 10Add 10 to each side:3x + 15 = 4xSubtract 3x from each side:15 = x
Presumably, this is an equation in finding the value of x 3x+5/4 = -2x+15 3x+1.25 = -2x+15 3x+2x = 15-1.25 5x = 13.75 x = 2.75
you plug in the value of y and solve for x by algebra For example, standard form is y = mx + b Say y = 3x + 4 and you are given y = 7 then 7 = 3x + 4 3 = 3x 1 = x x = 1
