Question

if George had3 marbles more he would have twice as much as Miguel if George had 4 marbles less he would have the same amount how much marbles does George have a.14 b.11 c.7 d.4 e.15​

Answer 1

b. 11

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.
