Answer:

x = 1.636364

Step-by-step explanation:

0.7x = 1.8 − 0.4x

  • Simplify both sides of the equation

0.7x = 1.8 − 0.4x

0.7x = 1.8 + −0.4x

0.7x = −0.4x + 1.8

  • Add 0.4x to both sides

0.7x + 0.4x = −0.4x + 1.8 + 0.4x

1.1x = 1.8

Divide both sides by 1.1

1.1x / 1.1 = 1.8 / 1.1

  • x = 1.636364

Answer:

x = 1.636364

x = 1.64 (simplified)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.7x=1.8−0.4x

0.7x=1.8+−0.4x

0.7x=−0.4x+1.8

Step 2: Add 0.4x to both sides.

0.7x+0.4x=−0.4x+1.8+0.4x

1.1x=1.8

Step 3: Divide both sides by 1.1.

1.1x/1.1=1.8/1.1

x=1.636364

x = 1.64 (simplified)
