What else can I help you with?
6x plus 12 equals -78-9x?
In this equation, x=6.
3x plus 5y equals 21 -9x plus 4y equals -6?
Multiply first equation by 3: 9x + 15y = 63Add that and second equation: 19y = 57Divide by 19: y = 3, so x = 2
What are the factors of the equation 2x2 plus 10 equals 9x?
2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
What is the equation in slope-intercept form of 9x plus 3y equals 6?
9x+3y = 6 3y = -9x+6 y = -3x+2 which is now in slope-intercept form
What is the y intercept to 9x plus 3y equals -54?
9x + 3y = -54 3y = -9x - 54 y = -(3x + 18) Therefore, the y-intercept of this equation is y=-18.
How can you get coefficients that are equal for y. 3x plus 5y equals 7 2x plus 15y equals 11?
Multiply the first equation by 3 to give 9x + 15y = 21
6x plus 12 equals -78-9x?
In this equation, x=6.
How do you write 12 equals 9x plus 3 in linear equation?
If: 12 = 9x+3 Then: 12-3 = 9x And: 9 = 9x So: x =1
What does x equal in 9x 3 plus 12 equals 32?
no
