8(5c – 2) = 10(32 + 4c)
HW#7 – Eqns with no solutions or infinite solutions/ HW#8: Multi-step eqns
Infinite Solutions or All Numbers
-Since the expressions on each side of the equation are the same, this equation is an identity. It is true for all values of x.
-Plug in any for x. The left side will equals the right side. Try it, it really works!
2. No solution
Since -16 does not equal 320, this equation has no solution.

HW#9 – Literal Eqns
Infinite Solutions or All Numbers
-Since the expressions on each side of the equation are the same, this equation is an identity. It is true for all values of x.
-Plug in any for x. The left side will equals the right side. Try it, it really works!
2. No solution
Since -16 does not equal 320, this equation has no solution.

13. Directions:
On your tablets, you will be solving equations.
You will have 1-3 minutes to solve each problem (SHOW YOUR WORK – ALL STEPS!)
When you hear the timer go off, show me your tablets.

14. 6/15
k = 12

15. 5y – 4 = 9y + 8 y = -3 7/15 Step 1: Subtract 9y from both sides
Step 2: Add 4 to both sides
Step 3: Divide both sides by -4
y = -3

16. 8/15
The sum of six and four times d is the same as d minus nine. Solve for d.
6 + 4d = d – 9
d = -5

17. 9/15
3(2k – 2) = -2(4k – 11)
k = 2
