factorise 80 x + 30 need explaining clearly please
80 (x) + 30
80+30=110*
110(x)
30-110-80(x)
80-30=50-110=(x)+110+30+50/(x)
X has no solution
remember distributive
a(b+c)=ab+ac
reverse
ab+ac=a(b+c)
find a which is GCF
factor them and group
80x=22225x
30=235
GCF=25=10
a=10
80x+30=10(8x)+10(3)=10(8x+3)
