Let x be the number of rows.
We solve the equation: x * ( 2 + 3 ) = 150.
x * 5 = 150.
x = 150 ÷ 5 .
x = 30.
a. There are 2 * 30 = 60 seats on the left side of the plane.
b. There are 3 * 30 = 90 seats on the right side of the plane.

28.) 8x + 28 - 16y
Find the GCF (greater common factor) or the smallest number that divide
8, 28 and 16 ALLTOGETHER.
8 = 2 x 4
28 = 7 x 4
16 = 4 x 4, so 4 is the GCF: Now you take 4 as a common factor
4(2x + 7 + 4y)
