How do you solve y equals 12x plus 5x-7?
y = 12x + 5x - 7 Since '12x' and '5x' both have the same variable, you are able to combine them. To do this you just need to add 12 + 5 to get 17. After doing this you can rewrite the equation as y = 17x - 7. You can then solve this equation for different values by plugging in a number for 'x' or 'y' or graphing the equation.
What is the solution to this equation 5x equals -60?
65
How do you solve 5x equals 18 plus 5x?
That equation has no solution. There is no possible number that's equal to 18 more than itself.
How do you solve 3 times 2 times 2 times 5x equals 60?
(3)(2)(2)5x=60 12(5x)=60 12(5x)/12=60/12 5x=5 x=1
How do you answer 2x plus 6y equals 32 and 5x-2y equals 12 using subtitution?
First, change 2x+6y=32 to x+3y=16. Then solve for x, which is x=-3y+16. Then substitute -3y+16 as x into 5x-2y=12 and solve for y. 5(-3y+16)-2y=12 -15y+80-2y=12 -17y+80=12 -17y=-68 y=4 Then substitute 4 as y in either equation to solve for x. 5x-2(4)=12 5x-8=12 5x=20 x=4 The answer is x=4 and y=4, or (4,4)
