Question

value of x when 1.8-3.7x=-4.2+0.3

Answer 1

Simplifying
1.8 + -3.7x = -4.2x + 0.3

Reorder the terms:
1.8 + -3.7x = 0.3 + -4.2x

Solving
1.8 + -3.7x = 0.3 + -4.2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4.2x' to each side of the equation.
1.8 + -3.7x + 4.2x = 0.3 + -4.2x + 4.2x

Combine like terms: -3.7x + 4.2x = 0.5x
1.8 + 0.5x = 0.3 + -4.2x + 4.2x

Combine like terms: -4.2x + 4.2x = 0.0
1.8 + 0.5x = 0.3 + 0.0
1.8 + 0.5x = 0.3

Add '-1.8' to each side of the equation.
1.8 + -1.8 + 0.5x = 0.3 + -1.8

Combine like terms: 1.8 + -1.8 = 0.0
0.0 + 0.5x = 0.3 + -1.8
0.5x = 0.3 + -1.8

Combine like terms: 0.3 + -1.8 = -1.5
0.5x = -1.5

Divide each side by '0.5'.
x = -3

Simplifying
x = -3

Answer 2

Let's solve your equation step-by-step.1.8−3.7x=−4.2+0.3Step 1: Simplify both sides of the equation.
1.8−3.7x=−4.2+0.3
Simplify:
1.8+−3.7x=−4.2+0.3
−3.7x+1.8=(−4.2+0.3)(Combine Like Terms)
−3.7x+1.8=−3.9
−3.7x+1.8=−3.9
Step 2: Subtract 1.8 from both sides.
−3.7x+1.8−1.8=−3.9−1.8
−3.7x=−5.7
Step 3: Divide both sides by -3.7.
−3.7x−3.7=−5.7−3.7
x=1.540541
Answer:
x=1.540541
