Answer:
Step-by-step explanation:
a+b=9500 equation 1
35a+55b=432500 equation 2
a=9500-b modified equation 1 to isolate a
35(9500-b)+55b=432500 substitute value of a in equ 1 into value of a equ 2
332500-35b+55b=432500
20b=100000
b=5000
solve for a
a + b=9500
a + 5000=9500
a=4500
check answer:
35a+55b=432500
35(4500)+55(5000)=432500
157500+275000=432500
432500=432500
