Supplementary angles add up to 180 degrees.
Let the larger angle be y and the smaller be x
y = 7x+4
And we know that
y+x = 180 Substitute for y
7x+4+x = 180
8x = 176
x = 22 The smaller angle is 22 degrees, and the bigger angle:
7*(22)+4 = 158

Since they are supplementary, they MUST add up to 180:
22+158 = 180
