Question

Solve for y. 7y - 6y - 10 = 13 y = -23 y = -3
y = 3
y = 23

Answer 1

Answer:

7y - 6y - 10 = 13 y

for y = -23

LHS = 7 x (-23) - 6 x (-23) - 10

= -161 - 138 - 10

= -33

RHS = 13

LHS not equal to RHS

For y = -3

LHS = -13

not equal to RHS

y = 3

LHS = -7 which is not equal to RHS

y = 23

LHS = 13 which is equal to RHS

Step-by-step explanation:

substitute the values for y and check whether LHS = RHS if so then that is the required answer.("⌒∇⌒")
