What's the next step?
3x + -1 = -5x + 4
Move the variables (like terms) to one side. Add 5x to both sides. 8x + -1 = 4
5a+1=4a+3
a = 4
3 + 5b = 8b - 9
b = 4
2x2x2x2 in exponent form
24
Which vocabulary word means a letter that represents a number?
Variable
What is the next step to solve this? (3x + 5x) + 2 = 6x - 1
Combine Like Terms. Add 3x + 5x and make it 8x. 8x + 2 = 6x - 1
a+4=2a-6
a=10
Solve for y: -6b + 24 = -60 + b
y = 12
eleven more than two times a number equals sixteen
2n+11=16
What math word means opposite operation?
Inverse operation.
What is the next step? 11x +7 = -71
Get the variable by itself by moving the whole numbers to the same side. 11x = -77x
2a + 2 = 5a + 11
x = -3
13b+2=11b+6
b = 2
Rational or Irrational: √85
Irrational
Which vocabulary word means that a number has a FIXED value.
Constant
What is the first step? -5x = -8x - 4
Move the variable to one side. So, add 8x to both sides. 3x = -4
-3 - 4a = 21 - 8a
x = 6
-9b + 8 = 48 + b
b = -4
A number that is multiplied by the variable
Coefficient
Which vocabulary word means that you combine terms that have the same variable or power?
Like terms
What is the first step? 3(x - 1) = 4x
Use the distributive property. 3x - 3 = 4x
2a + 12a - 8 = 11a + 1
x = 3
Solve for y: -6b + 14b - 280 = -9b + -127
b = 9
x2=4
x= -2, 2
Which vocabulary word means that you use the inverse operations (+, -, x, /) to get a variable alone.
Isolate the variable
