It is a linear equation in three variables which is equivalent to a linear equation in two variables. This is because 3 + e = 2.3f +e - 7g is equivalent to 3 = 2.3f -7g

-0.8 or -4/5 is the solution to the equation -2g + 4 + 7g.
4
(g + 5)(g + 2)
That depends what the value of g is.
12g + 20h You could write this as 4(3g + 5h)
12g
g = (-1). 18 + 6g = -12g 18 = -12g - 6g 18 = -18g -1 = g
7g + 4 = 4 subtract 4 from both sides 7g = 0 divide both sides by 7 g = 0
8a + 5g
16g - 7
