Answer:
x=-11/2
y=-11/2
Explanation:
Given equations are
y=3x+11 eq(1)
and 5x+3y=-44 eq(2)
Subtitute eq(1) into eq(2) we get
5x+3(3x+11)=-44
5x+9x+33=-44
14x+33=-44
Adding -33 to both sides of equation we get
14x+33-33=-44-33
14x+0=-77
14x=-77
Multiplying by 1/14 on both sides of the equation we get
1/14×14x=1/14(-77)
x=-77/14
x=-11/2
Put the value of x in the eq(1)
y=3(-11/2)+11
y=-33/2+11
Taking LCM
y=(-33+22)/2
y=-11/2.
