9x plus 8y
3x - 8y + 2x - 5 - 5y = 5x -13y - 5
140x / 64y divide 5x/8y = > 40x/64y X 8y/5x Note the change of sign and the inversion of the Right hand fraction. Cancel down by '5x' 8/64y X 8y/1 Cancel down by '8y' 8/8 X 1/1 = 8/8 = 1 The answer!!!!
7 + 8y - 3y + 2 =7 + 2 + 8y - 3y = 9 + 8y - 3y = 9 + 5y
8y + 7y = 15ySo [ 8y + 9 + 7y ] = 15y + 9If you want to get fancy and factor that expression, it's 3(5y + 3) .
9x plus 8y
5x+8y = 40 8y = -5x+40 y = -5/8x+5 in slope intercept form
It is: x-5y simplified
-5(x + 2y) -3x + 8y + 5 = -5x -10y -3x + 8y + 5 = -8x -2y + 5
3x - 8y + 2x - 5 - 5y = 5x -13y - 5
The given expression can be simplified to: x-5y
To determine slope and Y intercept, solve the equation for y... 5x - 8y + 64 = 0 -8y = -5x - 64 8y = 5x + 64 y = 5/8x + 8 ... now that you have the equation in the form y = mx + b, you can easily see that the slope is 5/8, and the Y intercept is 8.
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
140x / 64y divide 5x/8y = > 40x/64y X 8y/5x Note the change of sign and the inversion of the Right hand fraction. Cancel down by '5x' 8/64y X 8y/1 Cancel down by '8y' 8/8 X 1/1 = 8/8 = 1 The answer!!!!
(5x -3x) (2y +8y) 2x + 10y
Two algebraic terms
x = 8y = 6(5x8) + (3x6) = 58(5x8) - (3x6) = 22
