Question

0.3x + 0.4= 0.28x + 1.16

Answer 1

Answer:

0.3x + 0.4 = 0.28x + 1.16

bring like terms to one side

0.3x - 0.28x = 1 .16 - 0.4

( 0.30 - 0.28 )x = 1.16 - 0.40

0.02x = 0.76

x = 0.76/0.02

Multiply Numerator and denominator by 100 to remove decimal!

x = 0.76 × 100 / 0.02 × 100

x = 76/2

x = 38

Answer 2

$0.3x + 0.4 = 0.28x + 1.16 \\ \\ \implies \: 0.3x - 0.28 x= 1.16 - 0.4 \\ \\ \implies0.02x = 0.76 \\ \\ \implies \: x = \frac{0.76}{0.02} \\ \\ \implies \: x = \frac{76}{2} \\ \\ \implies \: x = 38$
