The equation that represents the sum of their ages is x + x + 1 = 7. By combining like terms, the equation becomes 2x = 6. Hence, the value of x which represents the age of Maria is 6 / 2 = 3. So Mariu is 3 + 1 = 4 years old.
 The question and answer: <ibo> N'iburu n'uche usoro nke echiche, nye ajụjụ na azịza ezi uche dị na ya. Ihe kpatara ya: Ọ bụrụ na x bụ afọ ole Maria dị, mgbe ahụ, afọ ole Mario dị bụ x + 1. Ngwakọta nke na-anọchi anya nchikota nke afọ ndụ ha bụ x + x + 1 = 7. Site n'ijikọta okwu ndị yiri ibe ha, nha anya ahụ na-aghọ 2x = 6. N'ihi ya, uru nke x nke na-anọchi anya afọ ndụ Maria bụ 6 / 2 = 3. Ya mere, Mariu dị afọ 3 + 1 = afọ 4.  Ajụjụ na azịza:
