x=2ab+7 x= 2(3)(5) +7 x=30+7 x=37
Yes. This is a logical deduction based on substitution. if x + y = 7 and y = 5 then the value of 5 can be substituted for y to get x + 5 = 7 which can then be solved to get x = 2, meaning the point (2, 5) is a solution to the line x + y = 7 as it is on that line.
If: 3x-7+x = 5 Then: x = 3
x = 2
2
5-x equals 7 = -2
5 x 7 and 6 x 7
(x + 7)2 = 5 x + 7 = ±√5 x + 7 - 7 = -7 ± √5 x = -7 ± √5
x=2ab+7 x= 2(3)(5) +7 x=30+7 x=37
Yes. This is a logical deduction based on substitution. if x + y = 7 and y = 5 then the value of 5 can be substituted for y to get x + 5 = 7 which can then be solved to get x = 2, meaning the point (2, 5) is a solution to the line x + y = 7 as it is on that line.
If: 3x-7+x = 5 Then: x = 3
x = 2
7 x 1?
0.714285 x 7 = 5
5 x 5 x 7 x 7 and the other one is 1 x 5 x 7 x 35
1 x 35, 5 x 7, 7 x 5, 35 x 1.
4x-7=5x-2 x=-5
