Question

solve the following systems of simultaneous linear equations by the substitution method.
3x + 4y = 37
5x + 2y = 43​

Answer 1

Answer:

x=7

y=4

Step-by-step explanation:

3x+4y=37

5x+2y=43 ×2

___________

3x+4y=37

10x+4y=86

- - -

___________

-7x = -49

x = 7

3(7)+4y= 37

4y= 37-21

4y=16

y=4
