• Yes, it is a solution.

• No, it is not a solution.

Determine whether the given value of the variable is a solution.
b ⋅ 5 = 20, when b = 3

• yes

• no

Is x=2 a solution of the equation : 2x^2-x+9=x^2+4x+3

• YES

• NO

Which of the following values for x is a solution to the equation below?
-3(2-4x)+2(-5x+3)=-8x+6x+20

• -4

• 5

• 2/3

• 2
  

• 3/4

Tell whether s=79

s=79 is a solution to s−68=11

s−68=11.

• Yes

• No

3x+50=5

• x=0

• x=2

• x= 45

• X=-15

Solve the equation: 2x + 5 = 15

• x = 5

• x = 10

• x = 7

• x = 8

Solve.

5h - 25 = 45

h=?

Answer explanation

Get the variable by itself. Do the opposite of the two operations you see. Add 25. Divide 5.

3c + 5 = 23

• 6

• 7

• 2

• 4

For this problem, what do you do first?

9x -18=27

• Add 18 to both sides

• Subtract 18 from both sides

• Divide 9 from both sides

• Multiply 9 from both sides
