Answer:
Step-by-step explanation:
Simplify the numerator and the denominator.
Answer:
77y-44
Step-by-step explanation:
when you expand this type of equations you just multiply the coefficient of y and the number by -11
so:
-11*4=-44
-11*-7=77 (note: negative multiplied by negative equals positive)
so the equation now became
-44+77y
exchange places now its:
77y-44
Answer:
Step-by-step explanation:
Subtract equation 2 from equation 1
.7x+y-(-1.5x+y)=340-320
.7x+y+1.5x-y=20
2.2x=20
x=100/11, then use this in either original equation to find y.
.7(100/11)+y=340
y=3670/11, so the balance point is
(100/11, 3670/11)
