Find the solution of the system of equations.
-8x+5y=43
-8x+4y=36

Step-by-step explanation:

Given equations:

   Equation:1

    Equation:2

As the coefficients of 'x' are same which will eliminate the terms of 'x':

Subtracting Equation:2 From Equation:1

Putting value of 'y' in either equation:1 or 2

Putting y=7 in equation:2

Subtracting '28' from both side:

Changing the sides:

The values are :        

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
