Answer :
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?
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?
The value of x in the equation 1.8-3.7x=-4.2x+0.3 is - 3.
1.8 - 3.7x = -4.2x + 0.3
add 3.7x to both sides
1.8 - 3.7x + 3.7x = -4.2x + 3.7x + 0.3
1.8 = -0.5x + 0.3
subtract 0.3 from both sides
1.8 - 0.3 = -0.5x + 0.3 - 0.3
1.5 = - 0.5x
divide both sides by - 0.5x
1.5 / -0.5 = -0.5x / -0.5
x = - 3
