Establish variables
x = melinda
y = barbara
...
Given
x = y - 154
x + y = 396
...
Substitute x into the second equation
y - 154 + y = 396
...
Combine like terms
2y = 396 + 154
2y = 550
...
Divide both sides by 2
highlight_green%28y+=+275%29 made by Barbara
...
Substitute y = x+154 into the second equation
x + x+154 = 396
...
Combine like terms
2x = 396 - 154
2x = 242
...
Divide both sides by 2
highlight_green%28x+=+121%29 made by Melinda
...
