It is an algebraic expression that can be simplified to: 5x+9y+5
If: 5x-9y = 7 and 7y-3x = -5 Then: x = 1/2 or 0.5 and y = -1/2 or -0.5
The slope of any line parallel to the line described is -5. Solution: 45x+9y=36. Solve for y. 9y=36-45x. y= -5x+4 m=-5
9y + 5 = 0 (-5 on both sides)9y = -5 (/9 on both sides)y = -5/9
5x - 9y = 43 (A)3x + 8y = 68 (B)(A)*3: 15x - 27y = 129(B)*5: 15x + 40y = 340Subtracting the first from the second gives67y = 211 => y = 211/67 = 3.15 approxSubstituting the [rational] value of y in (B)5x - 9*211/67 = 43 => 5x = 43 + 1899/67 = 4780/67therefore x = 956/67 = 14.27 approx.
