Solve the system of equation by using substitution method 2x5y=22 y=x5 6 Solve the system of equation by using substitution method y=2x1 5y6x=13 7Solve by substitution 8x2y=44 9x2y=58 8 Solve by using substitution x4=y 5x5y= 9 Solve by substitution method x5y=15 2x10y=16 10 Traffic signs are regulatedAnswer (1 of 2) If x y = 4, Then y = 4 x if y = 4 x Then 2x (4 x) = 5 by substituting y's value in terms of x into the equation 2x (4 x) = 5 2x 4 x = 5 x = 3 If you use the first equation, x y = 4 Then substituting x gives you 3 y = 4 Which means y = 1 So x = 3 an So, now we substitute 3 – 4y for the value of x in equation A Equation A is 3x 2y = 4 3x 2y = 4 3(3 – 4y) 2y = 4 Step 4 Perform the multiplication 3(3 – 4y) 2y = 4 (3 × 3) – (3 × 4y) 2y = 4 9 – 12y 2y = 4 Step 5 Perform inverse operations to solve for y 9 – 12y 2y = 4 9 – 9 – 12y 2y = 4 – 9 6 3 Substitution Method Simultaneous Linear Equations Siyavula X y/2 4 x/3 2y 5 substitution method
