There is no symbol between 43x and 2y.
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
2y^2+5y+2=(2y+1)(y+2)
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
5y explanaition 5x-5x=0, 0-2y=-2y, -2y+7y=5y
3y-8+5y = 2y-39 3y+5y-2y = -39+8 6y = -31 y = -31/6
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
2y^2+5y+2=(2y+1)(y+2)
5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
5y explanaition 5x-5x=0, 0-2y=-2y, -2y+7y=5y
Solving for y: 5y = 9 + 2y 5y - 2y = 9 3y = 9 y = 9/3 = 3
5y + (4 - 2y) = 9 5y + 4 - 2y = 9 3y + 4 = 9 3y = 5 y = 5/3
3y+2y+4+1=80 5y+5=80 5y=80-5 5y=75 y=15
3y-8+5y = 2y-39 3y+5y-2y = -39+8 6y = -31 y = -31/6
80 = 3y + 2y + 4 + 1 80 = 5y + 5 80 - 5 = 5y + 5 - 5 75 = 5y 75 / 5 = 5y / 5 15 = y
2y+5y=10 7y=10 y=10/7
(7x-3y) + (2x+5y) = 9x+2y
