Solve the equation by filling in the steps: 2(x−3)+21=−3
(4 points)
Step 1: Distribute to get
2x - 6 + 21 = -3
Step 2: Combine like terms to get
2x + 27 = -3
Step 3: Use
to get 2x=−18
Step 4: Use
to get x=−9
Step 1: Distribute to get 2x - 6 + 21 = -3
Step 2: Combine like terms to get 2x + 15 = -3
Step 3: Subtract 15 from both sides to isolate 2x:
2x + 15 - 15 = -3 - 15
2x = -18
Step 4: Divide both sides by 2 to solve for x:
2x/2 = -18/2
x = -9
Step 1: Distribute the 2 to both terms inside the parentheses:
2x - 6 + 21 = -3
Step 2: Combine like terms on the left side of the equation:
2x + 15 = -3
Step 3: Subtract 15 from both sides of the equation:
2x = -18
Step 4: Divide both sides of the equation by 2 to solve for x:
x = -9
