Solve the simultaneous equations: 3x+5y=3 and 6x+6y=10

(1): 3x+5y=3 (2): 6x+6y=10 Multiply number one by two to give a common factor of 6x in both equations. (3)=[2*(1)]- 6x+10y=6 Take away equation (2) from equation (3) to leave us with only y's and numbers so ...

Solve these simultaneous equations (2x+y=7 and 3x-y=8) and find the values of Equation: x and Equation: y .

-First of all add these two equations together so that the y s get eliminated. 5x=15 x=3 Since you have found the answer to x which is 3, substitute x into the equation 2x+y=7. 2*3+y=7 6+y=7 Therefore y=1 an...
