Solve the two simultaneous equations y+5x=30 and 6y=-x+64

The easiest way to solve these equations is by substitution. Rearrange the 6y=-x+64 equation into the form of x=64-6y. Replace x in the other equation with x=64-6y to produce y+5(64-6y)=30. Multiply out the brackets and rearrange to produce -29y=-290 so y=10. Substitute y=10 into the equation x=64-6y to get x=64-60 so x=4.
