write it as 2 separate equations:
12x-5y=30
2x-6=30
Now the easiest thing to do is solve the second equation:
2x=36
x=36/2
x=18
Now just plug x=18 into the first equation:
12*18-5y=30
216-5y=30
-5y=-186
y=37.2

12x - 5y equals 30 and y equals 2x - 6 what is the y value?
12x - 5(2x - 6) = 30 12 x - 10x + 30 = 30 2x = 0, x = 0 y = -6
How do you factor the expression 30 plus 12x equals?
30+12x = 6(5+2x)
Y equals 5-2x and 4x plus 6y equals -2 solve by substitution?
y = 5 - 2x so 4x + 6(5 - 2x) = -2 ie 4x + 30 - 12x = -2 Subtract 30 from each side: 4x - 12x = -32 ie -8x = -32 so x = 4 and y = -3
What does x equal in 2x squared plus 6 equals 30?
2x2 + 6 = 30 is your statement.2x2 = 24x2 = 12x = ±√12x = ±√(4*3)x = 2√3 or x = -2√3
What is the answer to 12x-30 equals 114?
12x-30=114 12x=114+30 x=144 / 12 therefore x=12
12x - 5y equals 30 and y equals 2x - 6 what is the y value?
12x - 5(2x - 6) = 30 12 x - 10x + 30 = 30 2x = 0, x = 0 y = -6
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
How do you factor the expression 30 plus 12x equals?
30+12x = 6(5+2x)
Use addition or substitution to find the value of x for this set of equations 12x-5 equals 30 and y equals 2x-6?
12x - 5 = 30Add 5 to each side:12x = 35Divide each side by 12:x = 35/12=======================y = 2x - 6Substitute the value of 'x' :y = 2(35/12) - 6Clear parentheses:y = 35/6 - 6y = 35/6 - 36/6y = -1/6
Y equals 5-2x and 4x plus 6y equals -2 solve by substitution?
y = 5 - 2x so 4x + 6(5 - 2x) = -2 ie 4x + 30 - 12x = -2 Subtract 30 from each side: 4x - 12x = -32 ie -8x = -32 so x = 4 and y = -3
What does x equal in 2x squared plus 6 equals 30?
2x2 + 6 = 30 is your statement.2x2 = 24x2 = 12x = ±√12x = ±√(4*3)x = 2√3 or x = -2√3
How do you solve the equation 2x plus 30 equals equals 12x-50?
Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x
