2) 0.4x + 3.9 = 5.78
2) 0.4x + 3.9 = 5.78
Answer
Explanation:
Step1: Subtract 3.9 from both sides
$0.4x+3.9 - 3.9=5.78 - 3.9$ $0.4x = 1.88$
Step2: Divide both sides by 0.4
$x=\frac{1.88}{0.4}$ $x = 4.7$
Answer:
$x = 4.7$
2) 0.4x + 3.9 = 5.78
$0.4x+3.9 - 3.9=5.78 - 3.9$ $0.4x = 1.88$
$x=\frac{1.88}{0.4}$ $x = 4.7$
$x = 4.7$
