7a=-310+3a equation

The teacher will be very surprised to see your correct solution 😉

You have entered [src]

7*a = -310 + 3*a

$$7 a = 3 a - 310$$

Simplify

Detail solution

Given the linear equation:

7*a = -310+3*a

Move the summands with the unknown a
from the right part to the left part:
$$4 a = -310$$
Divide both parts of the equation by 4

a = -310 / (4)

We get the answer: a = -155/2
