5x+8y = 40 8y = -5x+40 y = -5/8x+5 in slope intercept form
No, that is a equation.
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
x + 4y = 5Standard Form for a linear equation is Ax + By = C, where B is not = 0, A is >=0, A is an integer, and -preferably- A, B and C have no common factor. Sometimes ax + by + c = 0 is used instead.10 - 2x = 8y 10-2x-8y =0 -2x-8y=-10 2x+8y=10 x+4y=5.
3y - 20 = 8ySubtract 3y from each side:-20 = 5yDivide each side by 5:-4 = y
Well, honey, the value of y in 8y - 5 = 11 is simply y = 2. So, go ahead and plug that bad boy back into the equation and watch the magic happen. Math doesn't have to be a headache, just a little sassy fun!
5x+8y = 40 8y = -5x+40 y = -5/8x+5 in slope intercept form
No, that is a equation.
74 (10*5)+(8*3) = 74
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
If: 8y-2 = 3-2y Then: 8y+2y = 3+2 So: 10y = 5 Therefore: y = 5/10 or as a 1/2 in its simplest form
10y + 8y = 18y = 15 y = 15/18 y = 5/6 = 0.833333.....
If you mean 8y^2 +14y = 15 then the value of y is -5/2 or 3/4
To find the number that, when multiplied by 5, equals 55, you would divide 55 by 5. This calculation gives you the value of 11. Therefore, 11 times 5 equals 55.
(5 - 11y - 12) + 8y = 5 - 11y - 12 + 8y = ( - 7 - 3y )
-5(x + 2y) -3x + 8y + 5 = -5x -10y -3x + 8y + 5 = -8x -2y + 5
x + y = 82x - y = 5-------------------- add together to eliminate y3x = 13x = 13/3Substitute for x in one of the original equations:(13/3) + y = 8y = 24/3 - 13/3y = 11/3x=13/3 & y=11/3
