Question

PLEASE HELP ASAP! ITS DUE SOON AND PLS SHOW UR WORK HELP PLSPLSPLS

question: solve for the solution using substitution.

Answer 1

y=2x+10

Swap sides so that all variable terms are on the left hand side.

2x+10=y

Subtract 10 from both sides.

2x=y−10

Divide both sides by 2.

2

2x

​

=

2

y−10

​

Dividing by 2 undoes the multiplication by 2.

x=

2

y−10

​

Divide y−10 by 2.

x=

2

y

−5

SOLVE FOR Y

y=2(x+5)

6y=x−61

Swap sides so that all variable terms are on the left hand side.

x−61=6y

Add 61 to both sides.

x=6y+61

SOLVE FOR Y

y=

6

x−61

​

Answer 2

Explanation:

6(2x+ 10) = x - 61

12x + 60 = x - 61

11x + 60 = -61

11x = -121

x = -11

6y= -11 - 61

6y = -72

y = -12

(-11, -12)
