The given expression can be simplified to: x-12y
5y+8 = 7y-6 5y-7y = -6-8 -2y = -14 y = 7
5y+8=7y subtract 5y from each side , 5y+8=7y -5y -5y 8=2y /2 /2 4=y
5y+8=7y 2y=8 y=4
7y + 4 = 5y - 6Subtract 4 from each side:7y = 5y - 10Subtract 5y from each side:2y = -10Divide each side by 2:y = -5
5y explanaition 5x-5x=0, 0-2y=-2y, -2y+7y=5y
6y=5y+2y 6y=7y that does't work its unequal -
y = 14
(x + 5y)(x + 7y)
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
That factors to y(y2 + 7y - 5)
8y + 7y = 15ySo [ 8y + 9 + 7y ] = 15y + 9If you want to get fancy and factor that expression, it's 3(5y + 3) .
2y - 7 + 5y = 0 Collecting like terms together, 7y - 7 = 0 or 7y = 7 So that y = 1
