Given abcd ac=38 and ae=3x+4 find the value of x

Two times a number plus three times another number equals 4. three times the first number plus four times the other number is 7. find the numbers

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
