Bellwork: Friday Homework: TASK due next MONDAY

1-Step Equations 7. EE.4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

Vocabulary Equation- a math sentence stating that 2 quantities are EQUAL Solution- the value of the variable that makes an equation true (the answer) Equivalent Equations- equations with the same solution

Isolate Inverse Operation TWO for Solving Equations + undoes – Get the variable alone on one side of the equation Inverse Operation Operations that “undo” each other + undoes – undoes + x undoes ÷ ÷ undoes x

x + 5 = 14. Isolate the Variable (circle the. operation x + 5 = 14 Isolate the Variable (circle the operation and number that are “in the way”) -5 -5 Inverse Operation ( - undoes + ) x = 9 check: 9 + 5 = 14

Watch for the signs. Remember the sign comes IN FRONT of the term!! x - 5 = 14 Isolate the Variable +5 +5 Inverse Operation ( + undoes - ) x = 19 check: 19 - 5 = 14

Watch for the signs. Remember the sign comes IN FRONT of the term!! You Try: x + 8 = 11 Isolate the Variable Inverse Operation x = 11 check: ___ + 8 = 11

Watch for the signs. Remember the sign comes IN FRONT of the term!! You Try: 23 = x - 11 Isolate the Variable Inverse Operation check:

Watch for the signs. Remember the sign comes IN FRONT of the term!! You Try: x + 11 = 23 Isolate the Variable Inverse Operation ( + undoes - ) check:

Watch for the signs. Remember the sign comes IN FRONT of the term!! 𝑋 6 = 10 Isolate the Variable (6) 𝑥 6 = 10 (6) Inverse Operation (x undoes ÷) x = 60 check: 60 6 = 10 10 = 10

Watch for the signs. Remember the sign comes IN FRONT of the term!! 16 = 8x Isolate the Variable 16 8 = 8𝑥 8 Inverse Operation (÷ undoes x) 2 = x check: 16 = 8(2) 16 = 16

Watch for the signs. Remember the sign comes IN FRONT of the term!! You Try: 9x = 54 Isolate the Variable Inverse Operation check:

Watch for the signs. Remember the sign comes IN FRONT of the term!! You Try: 𝑋 2 = 12 Isolate the Variable Inverse Operation check:

Watch for the signs. Remember the sign comes IN FRONT of the term!! Practice 1.) 8 + b = 16 4.) 𝑛 12 = 6 2.) c + 27 = 45 5.) 3p = 27 3.) 20 = m – 12 6.) 𝑑 14 = 7
