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.
How do you solve 3x plus 5x equals 32?
add 3x and 5x together to make 8x. Then your equation will be 8x=32. Lastly, divide 8 to both sides which will make x=4.
How do you solve the equation of 5x 3 equals 12?
Assuming the sign of 3 is a minus: Add 3 to each side: 5x = 15 Divide each side by 5: x = 3 QED
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.
10x-18 equals 5x plus 2?
10x - 18 = 5x + 2 Add -5x + 18 to both sides of the equation, to get: 5x = 20, from which x = 4.
