solve and check your answer-
a. x=4/5(x+10)
b. 2y+5/3=26/3-y
(A) x = 4/5*(x + 10)
=> x = 4x/5 + 8
=> x - 4x/5 = 8
=> (5x - 4x)/5 = 8
=> x = 8 * 5 = 40
Verification / Checking-
LHS = x = 40
RHS = 4/5*(x + 10) = 4/5*(40 + 10) = 4/5 * 50 = 40
. .. LHS = RHS
Thus, verified/checked.
(B) 2y + 5/3 = 26 /3 - y
=>2y + y= 26/3 - 5/3
=> 3y = (26-5)/3
=>y = 7/3
Verification / check -
LHS = 2y + 5/3 = 2* 7/3 + 5/3 = 14/3 + 5/3 = 19/3
RHS = 26/3 - y = 26 /3 - 7/3 = 19/3
Since, LHS = RHS
Thus, verified.
