Solve the simultaneous equations: 3x+2y=11, 2x-5y=1.

Step 1) Label Equations 1) 3x+2y=11 2) 2x-5y=1 Step 2) Multiply so that one variable has same coefficient in both equations.1)x5 15x+10y=55 2)x2 4x-10y=2Step 3) Add/Subtract equations to remove one variable. 1+2: 19x=57Step 4) Solve to find x x= 57/19 = 3Step 5) Sub x back into original equation to find y 3(3)+2y=11 2y=11-9 2y=2 y=1 x=3, y=2
