Question

Solve each of the given equations and show your work. If the equation has no solution or infinitely many solutions, circle that instead of writing an answer.
6. 2(x+3.5)-x=-3(6-2x) ANSWER: __________
no solution infinitely many solutions






7. -17+2(1+3x)=x-5(3-x) ANSWER: __________
no solution
infinitely many solutions







8. -2(x+4)+9x=4+7x ANSWER: __________
no solution
infinitely many solutions

Answer 1

Answer:

7) 4

Step-by-step explanation:

-17+2(1+3x)=x-5(3-x)

-17+2+6x=x-15+5x

-17+6x=x-15+2+5x

-17+6x-5x=x-13

x=x-13+17

x=x+4

x-x =4

0=4

Answer 2

6) 2(x+3.5)-x=-3(6-2x)
2x+7-x=-18+6x
x+7=-18+6x
x+6x=-18+7
7x=11
x=1 4/7

8) -2(x+4)+9x=4+7x
-2x-8+9x=4+7x
7x-8=4+7x
7x+7x=-8+4
14x=-4
x=-2/7
