Here's how to solve question 1 using the substitution method: Step 1: Write down the given equations. x + y = 10 ·s (1) x - y = 8 ·s (2) Step 2: From equation (2), express x in terms of y. x = 8 + y ·s (3) Step 3: Substitute equation (3) into equation (1). (8 + y) + y = 10 8 + 2y = 10 Step 4: Solve for y. 2y = 10 - 8 2y = 2 y = (2)/(2) y = 1 Step 5: Substitute the value of y back into equation (3) to find x. x = 8 + 1 x = 9 The solution is: x = 9 y = 1 Send me the next one 📸
