How do i do substitution if x is on the same side as y

1 answer:

5 0

Cancel out one kind of variable from that side and put it on the other side.

Examples:

5x + 5y = 15
---- - 5y ------- - 5y

5x = 15 - 5y

6c - 2b = 48
---- +2b -------- + 2b

6c = 48 + 2b

Hope this helps!

$11x +2 = 58 + 5x + 10$

Collect Like Terms

$11x -5x = 58 + 10-2$

$11x -5x = 66$

$6x = 66$

Divide through by 6

$\frac{6x}{6} = \frac{66}{6}$

$x = \frac{66}{6}$

$x = 11$
