If you mean: 3x+2y = 16 then it is y = -1.5x+8
If you mean: x^2+15-3x then its value is 19 when x equals 4
If you mean: y = 3x+1 then the value of y will equal 10
2x+3x = 5x
If: 3x = 15 Then: x = 5
[ y = -12 ] is.
If you mean: 3x+2y = 16 then it is y = -1.5x+8
The problem '3x+9=81-5' can be solved as follows - 3x+9=81-5x Original Problem 3x=72-5x Subtract 9 from both sides of the equation 8x=72 Add '5x' to both sides of the equation x=9 Divide both sides by 8
3x+12 = 18 3x = 18-12 3x = 6 x = 2
do you mean x2 + 3x + 2 ? Factors are (x +2)(x+1)
3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
5x-72
3x+27=12x-45 Bring x to one side and the numbers to the other 45+27=12x-3x 72=9x x=8 For any step you don't understand message me
no
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
3x-3x equal = 0
First of all, if 'x' is 3, then 'x' doesn't equal -3x+3 . You must mean y = -3x + 3.If x=3, then (-3x + 3) = -6 .The graph is the point (3, -6) .
