2x + 30 = 4x + 22
Subtracting 2x from both sides,
30 = 2x + 22
Subtracting 22 from both sides,
8 = 2x
Dividing both sides by 2,
4 = x
x = 4

If the angles of a triangle measure 2x 2x and x plus 30 then the triangle is?
X=30 2x+2x+x+30=180; All of the angles in a triangle always add up to 180. Therefore 5x+30=180; subtract 30 to be 5x by itself. Therefore 5x=150; divide by 5 to find x. Therefore X=30 2(30)+2(30)+30+30=180
What are the intercepts of 2x 3y-6z equals 30?
x: x = 15 y: y = 10 z: z = -5
What is the area of a rectangle with a length of 12 and a perimeter of 30?
First we have to find the width. Let the width be x: 2(12+x) = 30 24+2x = 30 2x = 30-24 2x = 6 x = 3 So the width is 3 units Area = length*width = 12*3 = 36 square units
What is 30 squared plus B squared equals 78 squared?
First you square root everything on both sides to cancel the squares. 30+B=78 Then subtract 30 from both sides to get B=48. So the answer is B=48
Find the coordinates of the x and y intercepts of -5x plus 6y equals 30?
-5x + 6y = 30At the x-intercept, y=0:-5x = 30 ==> x = -6At the y-intercept, x=0:6y = 30 ==> y = 5
How do you solve 7x plus 3y equals 30 -2x plus 3y equals 3 in an order pair?
(3,3)
How do you factor the expression 30 plus 12x equals?
30+12x = 6(5+2x)
What is 2x plus 30 equals 4x plus 10?
2x + 30 = 4x + 10 Subtracting 2x from each side, 30 = 2x + 10 Subtracting 10 from both sides 20 = 2x Dividing both sides by 2 10 = x x = 10
Y equals xsquared plus 2x-3?
-1
What does x equal in 2x plus 6-6x equals 30?
2x + 6 - 6x = 30= 6 - 4x = 30= -4x = 24= 4x = -24= x = -6
The sum of two numbers is 60 and the difference is 22 what are the numbers?
30 plus 30 equals 60 and 60 minus 38 equals 22
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
Does 12 plus 20 equals 10 equal to 4x plus 14 equals 2x 30?
I am having difficulty understanding your question. 12 + 20 = 10 is obviously false (12 + 20 = 32).If 4x + 14 = 2x + 30, then x must equal 8.
What is the answer for 3 plus 2x plus 30?
It can be simplified to: 2x+33
What does x equals if the sum is 8x plus 8 equals 2x plus 38?
Set up the equation and solve: 8x + 8 = 2x +38 (subtract 2x and 8 from both sides of the equation) 6x = 30 (divide both sides of the equation by 6) x = 5
2X what equals 30?
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
