What is the subsitution for 2x=12 & x-5y=-29

Answer: (6, 7) x = 6

y = 7

Isolate x in the first equation.

2x = 12 Divide by 2 to both sides

x = 6 Isolated x!

Substitute in (6) for x in the second equation.

(6) - 5y = - 29 Remove parenthesises

6 - 5y = - 29 Subtract 6 from both sides

-5y = - 35 Divide by - 5 to both sides

y = 7 Isolated y!

With x = 6 and y = 7:

(6, 7)
