Question

Rounding to nearest 10th

Answer 1

Given - the system of the equations as

`y=-2x+1\\y=-11x-3`

To find - the solution of the set of equation

Explanation- given the set and we can see that left hand side of the equation is equal.

we get

`-2x+1=-11x-3\\-2x+11x=-3-4\\9x=-7\\x=-7/9=-0.77`

we get

`y=-2(0.77)+1\\y=-1.54+1\\y=-0.54`

Hence the value is x =-0.77, y=0.54

Final answer- the value of x = 0.77, y = -0.54
