Explanation:

Don't worry we will take care of everything. It's easy. listen carefully

first of all write your questions carefully.

i think it should be like this-

y= -6x +43 ------ (i)

y= -8x -59---------(ii)

1. We have two unknowns x and y. and two equations .

2. CONCEPT:- there are several ways to solve it like.

  • Elimination method
  • multiplication method
  • substitution method ( we will go with this)

ACCORDING TO SUBSTITUTION METHOD:-

Simply, write the equation in term of single variable(unknown). * [ which is already done for us]

second step, substitute the expression of obtained variable in any one equation.

example: substitute the value of y from equation (i) in (ii)

we will obtained equation -

=> y= -8x -59 [ put value of y from (i) ]

=> -6x +43 = -8x -59

(solve and find x)

=> -6x +8x = -59 - 43

=> 2x = -102

=> x = -51

Third step in substitute method is, now substitute this obtained value of x in any equation (i) or (ii) to get unknown y.

y will be = 349

* your questions was wrong so i have made it by myself. if this does not match your question sorry from my side. buti have shown you the concept to solve this type of questions. You will be able to solve this by your self now by applying concepts.
