Solve the following equation for x. Round the answer to the nearest hundredth.

Serhud [2]

Hence, option D 4: x=-1.34 is correct

Further explanation:

In order to solve an equation in one varible we have to isolate the variable on one side of the equations

Given equation is:

$-1.2x=2(x+2.15)\\Simplifying\\-1.2x=2x+4.3\\Subtracting\ 2x\ from\ both\ sides\\-1.2x-2x=2x+4.3-2x\\-3.2x=4.3\\Dividing\ both\ sides\ by\ -3.2\\\frac{-3.2x}{-3.2}=\frac{4.3}{-3.2}\\x=-1.34375\\Rounding\ off\ to\ nearest\ 100th\\x=-1.34$

Hence, option D: x=-1.34 is correct
