Question

5.9x−4.2=9.4x+3.3

solve for x

Answer 1

in order to solve for x, we need to get the variables on the same side of the equation.
5.9x - 4.2 = 9.4x + 3.3
-4.2 = 3.5x + 3.3
-7.5 = 3.5x
x = -2.14

Answer 2

-2.14 or -15/7

Explanation:

5.9x - 4.2 = 9.4x + 3.3

[combine like terms]

[when going across the equation, + becomes -, vice versa]

-4.2 - 3.3 = 9.4x - 5.9x

-7.5 = 3.5x

[isolate x]

[when going across the equation, * becomes /, vice versa]

-7.5 / 3.5 = x

-2.14 = x [decimal]

-15/7 = x [fractional]
