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 ...
Osmosis is the passive movement of a solvent, for example water, through a semipermeable membrane, such as one of a living cell, into a solution of higher solute concentration than the starting solute con...
3 (y + 4) - 2 (4y + 1)= 3y + 12 - 8y - 2= (3y - 8y) + (12 - 2)= 10 - 5y
