Using elimination, we add the equations, but this time from left to right. This process wants to elimination a variable. So 2x plus -2x equals 0. Moving on the next variable, 6y plus -y is 5y. On to the last variable, 18 plus 12 is 30. So we have this equation, 5y=30. 30/5 is 6, so y=6. We plug 6 into y in one of the equations you choose. In this case, I'm going to use the first equation. Plugging 6, we have this equation, 2x plus 36 is 18. 18-36 is -18. We then have this equation, 2x=-18. We know -9 times 2 is -18, so our x value is -9, So, our y=6, and our x=-9.

Solve7+x/4=5 For x please show steps
seraphim [82]

7 + x/4 = 5 (common denominator is 4)

4(7+x/4) = 4 x 5  (distribute the 4 though parenthesis)

4 *7 +4x/4 = 4 x 5

4 * 7 + x = 4 x 5

28 + x = 4 x 5

28 + x = 20 (subtract the 28)

x = 20 - 28

x = -8
