What is the solution to X plus 15 equals 16?
x+15=16x=16-15x=1
X2 plus 15x equals -26?
x2 + 15x = -26x2 + 15x + 26 = -26 + 26x2 + 15x + 26 = 0 where a = 1, b = 15, and c = 26x = [-15 ± √(152 - 4(1)(26))]/2(1)x = (-15 ± √121)/2x = (-15 ± 11)/2x = (-15 + 11)/2 = -4/2 = -2 or x = (-15 - 11)/2 = -26/2 = -13
What should you do to eliminate the y-term from the top equation 15x plus 7y equals 4 5x plus 7y equals 2?
15x+7y = 4 5x+7y = 2 Subtract the bottom equation from the top equation to eliminate y which will leave you with: 10x = 2 Divide both sides by 10 to find the value of x: x = 2/10 = 1/5 in its lowest terms. Substitute the value of x into the original equations to find the value of y: Therefore: x = 1/5 and y = 1/7
15x plus 75 and 6xFind the value of x?
set formula:15x +75 = 6xbring x to left side:15x - 6x + 75 = 09x = - 75x = - 75/9
X plus 3y equals 4 -x plus 2y equals -4?
x=4 y=0
If 15x equals 360 then x equals?
If: 15x = 360 then x equals 360/15 = 24
Can you show me how to graph y equals -15x 60?
If you mean: y = -15x+60 then 15x+y = 60 When y = 0 then x = 4 When x = 0 then y = 60 Coordinates of the line are: (4, 0) and (0, 60)
Is 15x an algebraic equation?
No. An equation must be equal to something, that's why its called an equation. 15x = 60 is an equation, in which case x equals 4
Can you answer this 20 x-35 x equals?
55
What is 8x plus 7x equals 60?
x = 4 You have to add the 8x and 7x to get 15x and then divide 60 by 15 to get x by itself.
What is 15x-18 equals -2x-5?
Here is the answer with Steps: 15x - 18 = -2x - 5 15x = -2x + 13 17x = 13 x = 13/17 x ~ .764705882
What is the answer to 9x plus 7 equals 15x plus 1 and how do you find it?
9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.
What is 15x equals 45?
15x = 45 Solve for x by dividing both sides by 15. 15/15 x = 45/15 Simplify. x = 3
What is the answer to this math problem 3-15x equals 12?
X=-0.6
What is the answer to x-7 equals -14 x equals?
7
How do you solve 5x2 plus 15x equals 0?
5x2 + 15x = 0 5x(x + 3) = 0 therefore, x = 0 or x + 3 = 0 that is, x = 0 or x = -3
15x-3 equals 2x plus 1?
OK, SO 15x-3 = 2x+1 15x - 3 + 3 = 2x + 1 + 3 (add three to each side) 15x=2x+4 (simplIfy) 15x-2x=2x-2x+4 (subtract 2x from each side) 13x=4 (simplify) (13x/13)=(4/13) (divide each side by 13) x≈0.30769231
