What is the x value of 12x - 5y equals 30 y equals 2x - 6?
Substitute 2x - 6 for y in first equation: 12x - 5(2x - 6) = 30 ie 12x - 10x + 30 = 30 so 2x = 0 making x = 0 and y = -6
What is the ordered pair of 14x - 2y equals 78 2x - 2y equals 6?
You can answer this by the method of substitution, which means that you find what one variable equals and you substitute it into the second equation to find the other variable.14x-2y=78; solve for y-2y=78-14x; subtract 14x on both sidesy=-39+7x; divide both sides by -2y=7x-39Substitute 7x-39 for y in the second equation.2x-2(7x-39)=6; solve for x2x-14x+78=6; distribute the -2-12x+78=6-12x=-72; subtract 78 on both sidesx=6; divide both sides by -12Now go back to the first equation and for x, substitute 6. You can either substitute in 14x-2y=78 or the y=7x-39, but it's easier where you already have y isolated.y=7(6)-39y=42-39y=3You got that x=6 and that y=3; therefore, the ordered pair is (6,3).
2x - 6 4?
2x-6=4 6+4=2x 10=2x 10/2=x 5=x x=5
What is 2X plus 4 equals 10?
2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
What is the answer to '2x plus 6'?
2x + 6 = what? There is not enough information to solve for x.
How do you simplify the expression 6-2x-14x?
Collect terms. Constants with constants, variables with matching variables. 6 is a constant, and the rest are all x terms. 6 - 2x - 14x 6 + (-2x -14x) 6 + (-16x) 6 - 16x ■
6 plus parenthsis around -2x - 8 - parenthsis -3 plus 12x - parentsis -4y?
6+(-2x-8)-(-3+12x)-(4y)= 6-2x-8+3-12x-4y=1-14x-4y 1-14x=4y (1-14x)/4=y
5x-8 equals -2x plus 6?
5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
How do you list all factors of 6x2 plus 14x-12?
6x2 + 14x -12 = (3x - 2) (2x + 6). There they are.
How do you solve 14x-2y equals 78 2x-2y equals 6?
are those two different problems ? ... i am going to solve them as if they are 14x-2y=78 (re arange the terms to be easily solved) -2y=78-14x (times by -1) 2y= -78+14x (divide all terms by 2) y=-39+7x (so) y=7x-39 2x-2y=6 (re arange the terms to be easily solved) -2y=6-2x (times by -1) 2y=2x-6 (divide all terms by 2) y=x-6
What is 4x to the second power plus 14x plus 12?
4x2 + 14x + 12 = 2(2x2 + 7x + 6) = 2(2x + 3)(x + 2)
What is the answer to this expression 14x+6=6?
14x + 6 = 6 14x + 6 - 6 = 6 - 6 14x = 0 14x / 14 = 0 / 14 x = 0
4x2 plus 14x plus 12?
124 (?) Try to do it on the calculator on your computer * * * * * No, 4x2 + 14x + 12 is factorised, as follows: 4x2 + 14x + 12 = 2(2x2 + 7x + 6) = 2(x + 2)(2x + 3).

What is Negative 7x plus 3 equals negative 15 divided by 2 help?
x = 1.5 because -7x + 3 = -15/2 -14x + 6 = -15 (x2) -14x + 21 = 0 (+15) 21 = 14x (+14x) 3 = 2x (/7) 1.5 = x
