Step-by-step explanation:
6x-2y=5 ........... Equation 1
y=3x+7 ............. Equation 2
Substitute y that's Equation 2 into equation 1 and solve for x
That's
6x - 2( 3x + 7) = 5
6x - 6x - 14 = 5
6x - 6x = 14 + 5
6x - 6x = 19
0x = 19
Divide by 0
x is undefined
Since x is undefined y is also undefined which means that the system has no solutions
Hope this helps you
