Solve the following system by the elimination method. 1/5 x+y= 6/ 5 1/10x + 1/3 y= 7/10

By the elimination method, solving the equation we get x =-1, y  = 7/5

Explanation:

Let     be equation 1.

Solving the equation, we get  x+5 y=6   as equation 1

Similarly for equation 2,

we get, 3x + 10y = 21 as equation 2

Solving both equation,

Multiplying equation 1 by 3  

and subtracting both the equations

We get

Substituting the value of y in equation 1, we get  

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
