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
