Answer:
b = 10
Step-by-step explanation:
You can solve for b by dividing both sides by 1/5 because it will remove the 1/5 from the left side of the equation, but what you do to one side you must do to the other side as well.
(1/5b)/ (1/5) = 2/ (1/5)
b = 10
Answer:
x = 6
Step-by-step explanation:
7 + x - 15 = -2
⇒ x-15 +7 = -2
⇒ x -8 = -2
add 8 on both sides
⇒ x= -2 +8
∴x = 6

Answer:
b. 11
Step-by-step explanation:
You'll have two equations in this system. Let G represent George's marbles and M represent Miguel's marbles.
1. G+3=2M (George's marbles plus 3 equals twice of Miguel's)
2. G-4=M (George's marbles minus 4 equals Miguel's marbles)
We have an explicit M value, so we can use the substitution method. Substitute the second equation into the first for M: G+3=2(G-4).
After some algebra, you'll get G=11. George has 11 marbles.
