180+8x=160+6x help me find x
lianna [129]

Answer:

x = -10

Step-by-step explanation:

Step 1: Write equation

180 + 8x = 160 + 6x

Step 2: Solve for <em>x</em>

  1. Subtract 6x on both sides: 180 + 2x = 160
  2. Subtract 180 on both sides: 2x = -20
  3. Divide both sides by 2: x = -10

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

180 + 8(-10) = 160 + 6(-10)

180 - 80 = 160 - 60

100 = 100
