Answer:
(6b+4)/r=t
Step-by-step explanation:
b=(rt-4)/6
multiply by 6

add 4
6b+4=rt
divide by r
(6b+4)/r=t
Answer:
y=4,x=1
Step-by-step explanation:
4x+y=8
x+y=5
subtract equation 2 from equation 1
3x + 0=3
3x=3
divide both sides by 3
x=1
substitute for x=1 in equation 2
x+y=5
1+y=5
y=5-1(collecting like terms)
y=4
Step-by-step explanation:
This is a sequence of multiply by 2
3 6 12 24 48
3 + t^2 - 4 x there no further factor.
