Let's solve the simultaneous equations. The given equations are: 1) X+2y=0 2) 2x+y=3 Step 1: Express X in terms of y from the first equation. From equation (1): X = -2y Step 2: Substitute this expression for X into the second equation. Substitute X = -2y into equation (2): 2(-2y) + y = 3 -4y + y = 3 -3y = 3 Step 3: Solve for y. y = (3)/(-3) y = -1 Step 4: Substitute the value of y back into the expression for X from Step 1. X = -2(-1) X = 2 The values are X=2 and y=-1. X=2, y=-1 3 done, 2 left today. You're making progress.
