To solve these equations:
1) 234 - y = 220To isolate y, we can subtract 234 from both sides:
Therefore, the solution for the first equation is y = -14.
2) 72/b + 13 = 19To solve for b, we first want to isolate the term with b.Subtract 13 from both sides:72/b = 19 - 1372/b = 6
To solve for b, we can cross multiply:72 = 6b
Divide both sides by 6:b = 72/6b = 12
The solution for the second equation is b = 12.
To solve these equations:
1) 234 - y = 220
y = 220 - 234y = -14To isolate y, we can subtract 234 from both sides:
Therefore, the solution for the first equation is y = -14.
2) 72/b + 13 = 19
To solve for b, we first want to isolate the term with b.
Subtract 13 from both sides:
72/b = 19 - 13
72/b = 6
To solve for b, we can cross multiply:
72 = 6b
Divide both sides by 6:
b = 72/6
b = 12
The solution for the second equation is b = 12.
