6y equals 5y plus 2y can be simplified to 6y = 7y. To solve for y, subtract 7y from both sides of the equation, which gives 6y - 7y = 0. This simplifies to -y = 0, or y = 0.
3y-8+5y = 2y-39 3y+5y-2y = -39+8 6y = -31 y = -31/6
9y-3y=6y; 6y+2y=8y; so your answer is 8y
6y + 2 = y + 17 => 5y = 15 => y = 3
x + 2y = 2.90 => x = 2.90 - 2y Substitue this value of x in the other equation: 3x + 5y = 7.60 3*(2.90 - 2y) + 5y = 7.60 8.70 - 6y + 5y = 7.60 1.10 = y and then substitute this value of y in either equation to find x: x = 2.90 - 2y = 2.90 - 2*1.10 = 2.90 - 2.20 = 0.70 Solution: (x, y) = (0.70, 1.10)
