Question:
Solve the equation:
4.3x − 0.7(x+ 2.1) = 8.61
A
x = 2.8
explanation
Original equation:
4.3x − 0.7(x+ 2.1) = 8.61
Apply the distributive property:
4.3x − 0.7x − 1.47 = 8.61
Combine like terms on the left side:
3.6x − 1.47 = 8.61
Add 1.47 to both sides:
3.6x = 10.08
Divide both sides by 3.6:
x = 2.8
