x-16=36
The commutative property of addition.
R+14=39
The answer to this equation is 37+22=61
x + 7y = 39 So x = 39 - 7y Substitute for x in the second equation: 3(39 - 7y) - 2y = 2 117 - 21y - 2y = 2 115 = 23y y = 5 Substitute this value for y back into the first equation: x + 7*5 = 39 x + 35 = 39 x = 4
r + 14 = 39 r = 25
The commutative property of addition.
39+39=78The equation "what is 39 plus 67" has an answer of 106.
R+14=39
R+14=39
39
The answer to this equation is 37+22=61
x + 7y = 39 So x = 39 - 7y Substitute for x in the second equation: 3(39 - 7y) - 2y = 2 117 - 21y - 2y = 2 115 = 23y y = 5 Substitute this value for y back into the first equation: x + 7*5 = 39 x + 35 = 39 x = 4
r + 14 = 39 r = 25
From first equation: x = 39 - 7ySubstitute this in second equation: 3(39 - 7y) - 2y = 2ie 117 - 21y - 2y = 2ie 115 = 23yie y = 5, making x = 4.
25
It is a linear equation in one variable, a.
39-14=25 so R=25 25+14=39
