What is the solution to the system of equations below? X+ 3y = 15 and 4x+2y= 30

O (6,3)

O (3,6).

O (7,-6)

O (-6, 7)

6,3

Step-by-step explanation:

given equtions are

x+3y=15(1)

4x+2y=30(2)

multiplying (1) by 4

on solving, 4x+12y=60(3)

substracting eqution (3) and (2)

4x+12y-(4x+2y)=60-30

⇒10y=30

on solving,

y=3

substituting the value of y in equation (1)

x+3(3)=15

on solving,

x=6

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
