Answer:
x = 0.2
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
3.5 + 1.2(6.3 - 7x) = 9.38
Step 2: Parenthesis (distribute)
3.5 + 7.56 - 8.4x = 9.38
Step 3: Combine like terms (constants)
11.06 - 8.4x = 9.38
Step 4: Subtract 11.06 on both sides
-8.4x = -1.68
Step 5: Divide both sides by -8.4
x = 0.2
