Substitute 5 for x and solve: 8 + 6(5) = ?
6x - 3b + 8 = 16.Since you cannot simplify the equation, the answer is 6x - 3b = 8.However, if you would like to find x, you can substitute b with '0':6x - 3b + 8 = 166x - 3b = 86x - 3(0) = 86x = 86 6x = 1.33 or 1(1/3)If you want to find b, you can substitute x with '0':6x - 3b + 8 = 166x - 3b = 86(0) - 3b = 8-3b = 8-3 -3b = -2.66 or -2(2/3)
To solve the equation for either y or x, you need to have a value for the variable you are not trying to solve for. For example, if you're solving for x in y = -6x + 1, when y = 0: 0 = -6x + 1 (substitute 0 for y) 6x = 1 (add 6x to both sides) x = 1/6 (divide both sides by 6)
If you mean: -10+4y = 12 then it is y = 2.5x+3
From first equation y = 3x + 5. Substitute this in second equation 2(3x + 5) = 6x + 10 This proves that 6x + 10 = 6x + 10 which is not helpful! I suppose possible solutions would be x = 0, y = 5 or x = 1, y = 8 etc etc Are you sure of your two equations, please?
