Answer:
None
Step-by-step explanation:
4a-9b=22
substitute b=-2
4a -9(-2) = 22
4a +18 =22
subtract 18 from each side
4a = 4
divide by 4
a =1
Choice C
Answer:
u = 5/4
Step-by-step explanation:
to evaluate for the value of u we would simply open the bracket and then evaluate for the value of u by collecting the like terms together.
solution
3=7(4 - 2u)-6u
3 = 28- 14u - 6u
collect the like terms
3 + 14u + 6u = 28
20u = 28 - 3
20u = 25
divide both sides by the coefficient of u which is 20
20u/20 = 25/20
u = 5/4
