10. Since we got the value of X that is equivalent of 78.
We will do Eq. 1 and 2 to solve the problem.
• 𝒙 − 𝒚 = 𝟔𝟎
• 𝟕𝟖 − 𝒚 = 𝟔𝟎
• −𝒚 = 𝟔𝟎 − 𝟕𝟖
• −𝒚 = −𝟏𝟖
• 𝒀 = 𝟏𝟖
Therefore the value of Y is 18
• 𝒙 + 𝒚 = 𝟗𝟔
• 𝟕𝟖 + 𝒚 = 𝟗𝟔
• 𝒀 = 𝟗𝟔 − 𝟕𝟖
• 𝒀 = 𝟏𝟖
• Therefore the value of Y is 18
11. STEP 4 (CHECKING)
Equation 1
𝑿 − 𝒀 = 𝟔𝟎
𝟕𝟖 − 𝟏𝟖 = 𝟔𝟎
𝟔𝟎 = 𝟔𝟎
Therefore the ans. Is correct
Equation 2
𝑿 + 𝒀 = 𝟗𝟔
𝟕𝟖 + 𝟏𝟖 = 𝟗𝟔
𝟗𝟔 = 𝟗𝟔
Therefore the ans. Is correct
The smaller number for this mathematical
problem is 18
