Which is the value of x in the solution to the following system of equations? x-y=-3 x+3y=5

x = -1

Step-by-step explanation:

The system of equations is given as x - y = -3 (1) and

x + 3y = 5 (2)

We have to find the value of x

For which we will eliminate y from these equations.

We multiply equation (1) by 3 and add it to equation (2)

3(x-y) + (x+3y) = -9 + 5

(3x + x) + (3y - 3y) = -4

4x = -4

x = -1

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
