Answer:
The smaller number is 28 and the larger number is 124.
Step-by-step explanation:
Let x = the smaller number
Let y = the larger number
x + y = 152
y - 4x = 12 Solve the second equation for y
y = 4x + 12 Substitute 4x + 12 for y into the first equation
x + y = 152
x + 4x + 12 = 152 Combine the x's
5x + 12 = 152 Subtract 12 from both sides of the equation
5x = 140 Divide both side of the equation by 5
x = 28 Substitute 28 for x in the first equation to solve for y
x + y = 152
28 + y = 152 Subtract 28 from both sides of the equation.
y = 124
6787.100 would be your answer.
