1 + 12 = WHAT
Yes that is correct
It is an equation and the value of x is 13/3
Taking it step by step: 2b - b - 10 = -13 b - 10 = -13 b = -13 + 10 b = - 3
multiply each side by 18 so that the denominator of 18 cancels and -6X18=b therefore b=-108
13
3x4+1
1 + 12 = 13
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
88=13+5x -13 -13 75= 5x 75/5 =15 x=15
It is a linear equation in one variable, x.
x+5=18 When you move 5 to the other side, you get x=13.
1 + 12 = WHAT
Equations: 7x+4y = 9 and 2x+3y = 1 Multiply all terms in the 1st equation by 2 and all terms in the 2nd equation by 7 So: 14x+8y = 18 and 14x+21y = 7 Subtract the 1st equation from the 2nd equation: 13y = -11 => y = -11/13 By substituting y = -11/13 into any of the equations x = 23/13 Therefore the solutions are: x = 23/13 and y = -11/13
5
If: m/4 = -13 Then by multiplying both sides by 4: m = -52
x+2y=13 has infinite answers, because you have two variables and only one equation.
