Solving the first equation: Combine like terms on the left side: 9b + 6b - 15 = 615 15b - 15 = 615 Add 15 to both sides: 15b = 630 Divide by 15: b = 42
Solving the second equation: Combine like terms on the left side: 17x - x + 5x - 19 = 170 21x - 19 = 170 Add 19 to both sides: 21x = 189 Divide by 21: x = 9
Therefore, the solutions to the equations are: b = 42 x = 9
Solving the first equation:
Combine like terms on the left side:
9b + 6b - 15 = 615
15b - 15 = 615
Add 15 to both sides:
15b = 630
Divide by 15:
b = 42
Solving the second equation:
Combine like terms on the left side:
17x - x + 5x - 19 = 170
21x - 19 = 170
Add 19 to both sides:
21x = 189
Divide by 21:
x = 9
Therefore, the solutions to the equations are:
b = 42
x = 9
