7x plus 8 equals 4x-10?
Presumably this is an equation in which the value of x is to be found. 7x+8 = 4x-10 7x-4x = -10-8 3x = -18 x = -6
What is 3x plus 2y equals 8?
3x + 2y = 8 This is an equation. It could be the equation of a line.
How do you Write the equation of the line that is parallel to y 3x plus 8 and passes through the point (-3 4).?
If you mean y = 3x+8 then the parallel equation will have the same slope and works out as y = 3x+13
What is the value of x if 5x - 3 equals 4 - 3x?
The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8
What is the value of the discriminant b2 and minus 4ac for the quadratic equation 0 and minus2x2 and minus 3x plus 8 and what does it mean about the number of real solutions the equation has?
If you mean 2x^2 -3x +8 = 0 then the discriminant works out as -55 which is less than 0 meaning that the equation has no real roots and so therefore no solutions are possible.
What is -10-3x equals 8-9x?
an equation
How do you work out what 3x plus 8 equals 12 is?
3x+8 = 12 Deduct 8 from both sides of the equation: 3x+8-8 = 12-8 3x = 4 Divide both sides of the equation by 3 to find the value of x: x = 4/3 or 1 and 1/3 Substituting the value of x into the original equation: 12 = 12
7x plus 8 equals 4x-10?
Presumably this is an equation in which the value of x is to be found. 7x+8 = 4x-10 7x-4x = -10-8 3x = -18 x = -6
What is 3x plus 2y equals 8?
3x + 2y = 8 This is an equation. It could be the equation of a line.
What is -3x plus 2 2x-8?
An equation, solution x = -10
What is 2x-2 equals 8 plus 3x?
An equation, solution x = -10
What would x and y be if the equation is 3x-4y equals 10 and -3x equals 4y equals 8?
3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
What is 22x plus 1 equals 3x plus 8?
It is an equation and the value of x is 7/19
3x+9=45 what is the value pf x?
In this equation, 3x + 9 = 45. To solve for x, you need to subtract 9 from both sides of the equation, which gives you 3x = 36. To find the value of x, you need to divide both sides of the equation by 3, which gives you x = 12. Therefore, the value of x is 12.
What is 3x equals 12?
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
What is x in the equation 3x plus 8 equals 20?
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
What is this equation in standard form 3x equals 6y plus 8?
3x-6y=-8
