Answer:
r = 3.
Step-by-step explanation:
16 = 10 + √(3r + 27)
√(3r + 27) = 6
Square both sides:
3r + 27 = 36
3r = 36 - 27 = 9
r = 3.
Check the result:
Left side of the equation = 16
Right side = 10 + √(9 + 27)
= 10 + √36 = 16
Answer:
1 solution (x = 1.5)
Step-by-step explanation:
2x + 2 - 3x = 3x - 4
First, combine like terms
2 - x = 3x - 4
Add 4 to both sides
6 - x = 3x
Add x to both sides
6 = 4x
Divide both sides by 4
1.5 = x
