Answer:

x = -7

Step-by-step explanation:

1 Regroup terms.

-2x+1=8-x−2x+1=8−x

2 Add 2x2x to both sides.

1=8-x+2x1=8−x+2x

3 Simplify 8-x+2x8−x+2x to 8+x8+x.

1=8+x1=8+x

4 Subtract 88 from both sides.

1-8=x1−8=x

5 Simplify 1-81−8 to -7−7.

-7=x−7=x

6 Switch sides.

-7 = x

x=−7

Hope this helps!

Solve the following system of equations using the substitution method.

BartSMP [9]

Answer:

Step-by-step explanation:

First label the equations.

6x +3y= 18 -----(1)

y= -2x +5 -----(2)

subst. (2) into (1):

6x +3(-2x +5)= 18

6x +3(-2x) +3(5)= 18 (expand)

6x -6x +15= 18

15= 18 (simplify)

(reject)

There is no solution.

<u>Further explanation</u><u>:</u>

If I rewrite the first equation into the form of y=mx+c, I would get

6x +3y=18

3y= 18 -6x (bring y term to one side)

y= 6- 2x (÷3 throughout)

y= -2x +6

Notice that the gradients of both lines are equal ( -2). This implies that they are parallel to each other and will never meet. Hence there are no solutions.
