Algebra 1 - 1 Step Equation
x + 5 = 12
x = the variable 5 = constant 12 = the answer
EQUATIONS HAVE AN EQUAL
SIGN AND ONLY ONE ANSWER!!!!
2x - 5 = 11
2 = The coefficient. It's any number before the variable.
x = the variable - = the constant 11 = the answer
x + 5 = 12
Step 1: Isolate the variable
Step 2 : Cancel using the opposite
Step 3: Balance the equation
Step 4: Simplify
Step 5: Verify
x + 5 - 5 = 12 - 5
x = 7
Let x = 7
x + 5 = 12
7 + 5 = 12
12 = 12
x - 7 = 3
Step 1: Isolate the variable
Step 2 : Cancel using the opposite
Step 3: Balance the equation
Step 4: Simplify
Step 5: Verify
x - 7 + 7 = 3 + 7
x = 10
Let x = 10
x - 7 = 3
10 - 7 = 3
3 = 3
3x = 15
Step 1: Isolate the variable
Step 2 : Cancel using the opposite
Step 3: Balance the equation
Step 4: Simplify
Step 5: Verify
3 divide by 3 and 15 divide by 3
x = 5
Let x = 5
3x = 15
3 (5) = 15
15 = 15
x divide by 2 = 4
Step 1: Isolate the variable
Step 2 : Cancel using the opposite
Step 3: Balance the equation
Step 4: Simplify
Step 5: Verify
2x divide by 2 = 4 divide by 2
x = 2
Let x = 8
x divide by 2 = 4
8 divide by 2 = 4
4 = 4
