Question

Write the equation y = 4x – 20 in Standard Form (AX + By = C) with integer coefficients

Answer 1

Answer:    4x - y = 20

=============================================

Work Shown:

y = 4x - 20

4x - 20 = y ...... swap both sides

4x = y + 20 ..... adding 20 to both sides

4x - y = 20 .... subtracting y from both sides

The equation is now in standard form (Ax+By = C) where,

• A = 4
• B = -1
• C = 20
