Assignment:
Find the solution to each system by the substitution method.
Q1.5x -2y=8 1(5x)-1(2y)=1(8) 5x-2y=8
3x - y=7 2(3x)-2(y)=2(7) 6x-2y=14
11x =22
X=
Y=
Find the solution to each system by the addition (elimination) method.
Q2. 12x – 5y= -7 2(12x)-2(5y)= 2(-7) 24x-10y=14
4x + 2y= 5 5(4x)+5(2y)=5(5) 20x + 10y=25
44x =39
x=
y=
If possible, solve each system of equations. Use any method.
Q3. 8x – y=17 3(8x)-3(y)=3(17) 24x-3y=51
4x + 3y=33 1(4x)+1(3y)=1(33) 4x+3y=33
28x =84
x= 3.5
8(3.5)-y=17
28-1y=17
-1y= -16
Y=16
Provide complete and step by step solution for the question and show calculations and use formulas.
