Write your answer in the following format:
with no spaces.

Answer 1

x = 7/10; y = 21/5

Explanation:

y = 6x

4x + y = 7

Since the first equation is already solved for y, we can easily use the substitution method. We substitute 6x for y in the second equation and solve for x.

4x + y = 7

4x + 6x = 7

10x = 7

x = 7/10

Now we use the first equation and substitute 7/10 for x and solve for y.

y = 6x

y = 6 * 7/10

y = 42/10

y = 21/5

Answer: x = 7/10; y = 21/5
