Answer:
a=4188 and b=1047
Step-by-step explanation:
the two sentences are put:
a= 4b
a + b = 5235
one of the two letters is replaced and said unknown is solved:
4b + b = 5235 (a+b=5235 where a=4b)
5b = 5235
b= 5235/5
b=1047
well! we have the first result now we replace the result in any of the equations and we will have the second result:
a=4b
a=4x1047
a=4188
