To solve the first equation: 287 + (120 - x) = 300 Combine like terms: 287 + 120 - x = 300 407 - x = 300 Subtract 407 from both sides: -x = -107 Divide by -1 to solve for x: x = 107
To solve the second equation: 2x - 267 = 133 Add 267 to both sides: 2x = 400 Divide by 2 to solve for x: x = 200
Therefore, the solutions for the two equations are: x = 107 and x = 200
To solve the first equation:
287 + (120 - x) = 300
Combine like terms:
287 + 120 - x = 300
407 - x = 300
Subtract 407 from both sides:
-x = -107
Divide by -1 to solve for x:
x = 107
To solve the second equation:
2x - 267 = 133
Add 267 to both sides:
2x = 400
Divide by 2 to solve for x:
x = 200
Therefore, the solutions for the two equations are:
x = 107 and x = 200
