Money invested S + B = $5000 - - - - (a)
Money earned can be represented in S & B as follows:
0.07*S + 0.14*B =$500 - - - - (b)
Equations a & b are two equations with two unknowns.
From equation a:
S = 5000 - B
Replace S in equation b
0.07*(5000 - B) + 0.14*B =$500
0.07B = 500 - 350 = $150
B = 150/0.07 = $2142.86
S = 5000 - 2142.86 = $2857.14
Good luck

GCF=2
Factor out the GCF.

Simplify.
2(x+5x+4)
Collect the like terms x and 5x.
2(6x+4)
Factor out the number 2, because 2*3=6 and 2*2=4.
2*2(3x+2)
Simplify to get the answer.
4(3x+2)
