Question

Solve the equation 5.9g + 4 = 3.9g + 12.

Answer 1

g=4

Explanation:

5.9g+4=3.9g+12

-4 -4

5.9g= 3.9g+8

-3.9g -3.9g

2g=8

/2 /2

g=4

Answer 2

Rearranging an equation:

• isolating for a variable (g)
• merge like terms and solve
• use inverse operations

`5.9g+4=3.9g+12`

`5.9g-3.9g=12-4`

`2g= 8`

`(2g)/(2) = (8)/(2)`

`g = 4`

g = 4
