2x + 3y = 1 y = 1/3 - 2x/3
y = -1
Y = 1 3(1) = 3 26 + 3 = 29
y + 2y = 4 (2+1)y = 4 3y = 4 (3y)/3 = 4/3 y = 4/3 = 1.3333333333333333333
x=1y=2x+3y=2*1 + 3y=5
2x + 3y = 1 y = 1/3 - 2x/3
y = -1
5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y
y=(x-1)/3
-3y + 6 = 7 Therefore, -3y = 1 Therefore, y = 1/-3 Therefore, y = -0.3 recurring (that is, -0.3333...)
-3
2y + 3 = 3y + 9 2y - 3y = 9 - 3 or -y = 6 so y = -6
Y = 1 3(1) = 3 26 + 3 = 29
y + 2y = 4 (2+1)y = 4 3y = 4 (3y)/3 = 4/3 y = 4/3 = 1.3333333333333333333
x=1y=2x+3y=2*1 + 3y=5
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
The problem to solve is: xy+x+3y+3 Multiply y and x Multiply the y and x Multiply y and x The y just gets copied along. The x just gets copied along. The answer is yx yx x*y evaluates to yx x*y+x evaluates to yx+x Multiply y and 3 Multiply y and 1 The y just gets copied along. The answer is y y 3*y evaluates to 3y The answer is yx+x+3y x*y+x+3*y evaluates to yx+x+3y The answer is yx+x+3y+3 x*y+x+3*y+3 evaluates to yx+x+3y+3 ---- The final answer isyx+x+3y+3----
