Question

The solution of equations system using the Substitution Method

y = 3x & 2y+2x=24 is (3,9)
true
or
false
help mee​

Answer 1

True

Explanation:

Plugging y = 3x in the equation 2y + 2x = 24, we find:

2(3x) + 2x = 24

6x + 2x = 24

8x = 24

x= 24/8

x = 3

Plugging x = 3 in the equation y = 3x we have:

y = 3*3 = 9

(x, y) = (3, 9)
