Subsitution is subsituting
y=3x-2
y=-x+6
subsitute 3x-2 for y in second equation
3x-2=-x+6
add x to both sides
4x-2=6
add 2 to both sides
4x=8
divide both sides by 4
x=2
subsitute
y=-x+6
y=-2+6
y=4
x=2
y=4
Numerator - numerator
denominator - denominator
What you need to do is the following:
Calculate the total number of identical twins which will be 2+2 = 4. and then total of twins is 12. The probability for her to have identical twins will be known with the following formula:
Identical twins = 4 / 12
that is 0.3333
The probability is 0.3333
