We are to solve this for x: 1.8-3.7x=-4.2x+0.3

Combine like terms. First, add 4.2x to both sides. This results in 1.8+0.5x = 0.3, and then 0.5x = 0.3-1.8.

Next, 0.05x = -1.5, or 5x = -150, and x = -30.

Must check this result by substitution of -30 for x in the original equation.

Is 1.8-3.7(-30)=-4.2(-30)+0.3 true or false?

Answer:

The answer is 3

Step-by-step explanation:

add -4.2 to -3.7 to get 0.5, then subtract 1.8 by 0.3 to get 1.5 on the other side. then you divide 1.5 by 0.5 to get 3. Hope this helps and have a good day!:)
