15x+25y = 315

25y = -15x+315

y = -0.6x+12.6 which is now in slope-intercept form

0-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2

-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2

9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.

23 + 15x - 4x = 1215x - 4x = 12 -2311x = -11x= -1

15X + 50 = 135 subtract 50 from both sides15X = 135-5015X = 85X = 5 and 2/3 or 17/3

x2 + 15x = 0x (x + 15) = 0x = 0x = -15

15x = -75, x = -5

If: 15x = 360 then x equals 360/15 = 24

15x minus 8=minus 180 3x+8=24

Do you mean? 3Y = - 15X + 6 Just divide all integers by 3 (3/3)Y = (- 15/3)X + 6/3 Y = - 5X + 2 ==============or. standard form 3Y = - 15X + 6 3Y + 15X = 6 ==============aY +bX = c

3x+12x = 15 15x = 15 x = 1

I think the question is asking "what value of y satisfies the equation 15x + 15y = 15x + y ? " If so, the answer is y = 0.

14x2 + 15x + 4 = (7x + 4)(2x +1)

x2+15x+14 = (x+1)(x+14)

y = -1.47585741 or y = 0.22585741 (to 8 dp)

No because the slope in both lines have different values

20x+7=5x+10 15x=3 3/15=.2 x=.2

5x2 + 15x = 0 5x(x + 3) = 0 therefore, x = 0 or x + 3 = 0 that is, x = 0 or x = -3

18x2 + 15x + 2 = (3x + 2)(6x + 1)

2x2 + 15x + 25 = (2x + 5)(x + 5)

In simple terms: 68-10x

x2-15x+56 = 0 (x-8)(x-7) = 0 Therefore: x = 8 or x = 7 To ensure that your answer is correct multiply out the brackets and you should go back to the original quadratic equation.

x = 2 and y =-3 so the lines intersect at (2, -3)

Sounds like a system of equations. Y + 5X = - 2 - 15X - 3Y = 6 substitution using first equation Y + 5X = - 2 Y = - 5X - 2 ==========insert into other equation as this is Y - 15X - 3(- 5X - 2) = 6 - 15X + 15X + 6 = 6 ========================This looks to be a dependent system that has an infinite number of solutions

When X = 4, 15X = 15 * X = 15 * 4 = 60
