Solve for m. -4.21 = m/3 + -7.8 m = ______________.

To solve the equation (-4.21 = frac{m}{3} – 7.8), follow these steps:

1. Isolate the term with m: Add (7.8) to both sides of the equation:

[

-4.21 + 7.8 = frac{m}{3}

]

[

3.59 = frac{m}{3}

]

2. Eliminate the fraction: Multiply both sides by (3) to solve for (m):

[

m = 3 times 3.59

]

[

m = 10.77

]

So, the solution is:

[

m = 10.77

]
