Apologies if I haven't set this out correctly.
Equation is V = U + AT
For EQ 1, V=21, T=3.5
For EQ 2, V=33, T=6.1
As you can see, equation 2 does not work out, however it will be correct if you do 34.3125 - 1.3125 = 33. I obviously need to do the subtraction but can't see where I need to change the positive to a negative.
I appreciate the help.
Thanks

Equation 1 (1) U + 3.5A = 21 (2) U = 21 - 3.5A (3) U = 21 - (3.5 * 5.625) (4) U = 21 - 19.6875 (5) U = 1.3125 | Equation 2 (1) U + 6.1A = 33 (2) 21 - 3.5A + 6.1A = 33 (3) 21 - 9.6A = 33 (4) 9.6A = 54 (5) A = 54/9.6 = 5.625 |
Verify 1.3125 + (3.5 * 5.625) = 21 1.3125 + 19.6875 = 21 | Verify 1.3125 + (6.1 * 5.625) 1.3125 + 34.3125 = 35.625 |
