... 3Y = 6 Y = 2. Now from equation (iv). 2 + Z = 2 => Z = 0. Substitute value of Y in (ii). X + 2 = 4 => X = 4 - 2 = 2. The solution is X = 2, Y = 2 and Z = 0. ...

... x=9 when y=2, find the value of y when x has a value of 15. 1. Solve this system of equations. Put your answer in alphabetical order. 5w+3x-yz=-2 w+x+y+z=2 2W-x ...

... this value of X in equation (5), we have 100-Y=0, hence Y=100. Using X=50, Y=100 in the equation (2), we have 400+200+Z=603. This gives Z=3. Hence the solution ...

... 10z - 4 = 86 10(9) - 4 = 86 90 - 4 = 86 86 = 86. Since the statement is true we have found the value for our variable z that solves this linear equation. II. ...
