A = 6
9=4a+13 9-13=4a -4=4a -4/4=a -1=a a=-1
a+a+a+a = 4a Because there're 4 a's so that equals = 4a
They appear to be the equations of two parallel lines in the a-b plane.
4a x 3
A = 6
9=4a+13 9-13=4a -4=4a -4/4=a -1=a a=-1
a+a+a+a = 4a Because there're 4 a's so that equals = 4a
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2

sqrt(4a2) = 21plus or minus (2a) = 21plus or minus (a) = 10.5a = +10.5a = -10.5
They appear to be the equations of two parallel lines in the a-b plane.
4a+5=25 4a=25-5 4a=20 a=20/4 a=5
4a x 3
4a-2=7a-6 4=3a a=4/3
4a + 2 = Answer let a = 2 then Answer equals 4(2) + 2 = 8 + 2 = 10.
a= -4
