Answer:
g = 5
Step-by-step explanation:
Expand brackets.
4g - 2 = 3g + 3
Add -3g and 2 on both sides.
4g - 3g = 3 + 2
Combine like terms.
1g = 5
Answer:
y = 3 1/13
Step-by-step explanation:
Add 3 and combine like terms:
... (2 3/5)y = 8
Multiply by the reciprocal of the coefficient of y.
... y = 8 · (5/13) = 40/13
... y = 3 1/13
_____
<em>Check</em>
(3/5)(3 1/13) - 3 + 2(3 1/13) = 5
(3/5)(40/13) - 39/13 + 2(40/13) = 5 . . . . express everything with 13 as a denominator
24/13 - 39/13 + 80/13 = 5 . . . . . eliminate parentheses
(24 -39 +80)/13 = 5 . . . . . . . . . . add the fractions
65/13 = 5
5 = 5 . . . . . the answer checks
