Identify Solution/Equations

When solving a system of equations algebraically, which statement results in no solution?

• 4 = 7

• -2 = 2

• -3 = 3

• all of the above

• (3, 1)

• Infinitely many solutions.

• (3, -2)

• (2, 1)

3(x-6)+2x=22

• x=8

• x=2

• x=18

• x=3

Identify the number of solutions the equation has. 
5x + 3 = 2x + 1

• one solution

• no solution

• infinitely many solutions

• two solutions

Identify the number of solutions the equation has. 
4x + 5 = 2(2x +3)

• one solution

• no solution

• infinitely many solutions

• two solutions

10x + 9 = 4x - 9

• 0

• 3

• -3

• -18

12+5w-4w=15

• w=1

• w=3

• w=5

• w=4

10(h+1)-4=76

• h=10

• h=4

• h=7

• h=76

I open a saving account with $200 and plan to put $50 per month in the account.
Which expression represents this situation after x number of months?

• 200 + 50x

• 200x + 50

• 200 + x + 50

Combine like terms and solve: 
4(y +4) = 46 – 2y

• x = 5 

• x = 6

• x = 7

• x = 8
