[ y = 2x plus or minus any number ] is parallel to it. [ y = -0.5x plus or minus any number ] is perpendicular to it.
3x-8+5x+39+4x+51 = x(3+5+4) + -8 + 39 + 51 = 12x +82
That will depend on the plus or minus value of 12 which has not been given.
x = 3.5
-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r
Spec is 39 psi plus or minus 5Spec is 39 psi plus or minus 5
39 psi plus or minus 539 psi plus or minus 5
There are two answers. Either -39 or -5
X=27
6
5
It can be: 5+10-5 = 10
It is possible.
it is minus 4 (-4) the right answer
Minus five, plus one, equals minus four.
If you mean: x+7y = 39 and 3x-2y = 2 Then by substitution: x = 4 and y = 5
13...... 9 plus 5 equals 14...... 14 minus 1 equals 13
