Question

.3x + 2y = 4
4x + 7y =1

Answer 1

x = 2
y = -1

Explanation:

Taking from the first equation:

2y = 4 - 3x
Dividing by 2:

y = 2 - 3/2x

Substituting:
4x + 14 - 21/2x = 1

4x - 10.5x + 14 = 1

-6.5x = -13

6.5x = 13

13x = 26

x = 2

Substituting:
6 + 2y = 4

2y = -2

y = -1

Checking our equation:

3x + 2y = 4

6 - 2 = 4

4x + 7y =1

8 - 7 = 1

Everything checks out, and I hope this helped.
