895 is approximately 90019.7 is approximately 20 900/20 = 45 it will take approximately 45 days to use all the oil in the tank

First, we gather like terms: 7x + 5x = -42 - 6 This gives: 12x = -48Now we can divide both sides by 12 to solve for x: 12x/12 = -48/12This gives: x = -4

To solve simultaneous equations we need to make either the y coefficients or the x coefficients equal so that we can cancel them out. For this set of equations we are going to make the x coefficients the ...

3 (y + 4) - 2 (4y + 1)= 3y + 12 - 8y - 2= (3y - 8y) + (12 - 2)= 10 - 5y
