1.) t + 4=-9
or t + 4 - 4 = - 9 -4 (subtracting 4 from either side)
or t = - 13

2.) 98=7z
Or (dividing by 7 on either side)
Or 14 = z
Or z = 14

3.) 37 = y/5 + 14
Or 37*5 = (y/5)*5 + 14*5 (multiplying by 5 on either side)
Or 185 = y + 14*5
Or 185 - 70 = y +70 - 70 (subtracting 70 from either side)
Or y = 115
