5+4x-7 = 4x+3-x
4x-2 = 3x+3
4x-3x = 3+2
x = 5
1x plus 3x equals 4x. When you combine like terms, you simply add the coefficients of the variables together. In this case, 1 + 3 equals 4, so the final result is 4x.
4x+3x-1x = 12 Collect like terms: 6x = 12 Divide both sides of the equation by 6 to find the value of x: x = 2
x = 15 as 4*15+6 = 66 3*15+21 = 66 or an easier way to do it 4x - 3x = 1x 21 - 6 = 15 1x = 15

-1x=5nSteps:3x-4x=5n like terms3-4=-1 add x -1x-1x=5n not like termsanswer -1x=5n
1x-5x = -4x But since you had the absolute value symbols surrounding it, change it to positive; so the answer is: 4x
x= -.5
You can't solve it. But you can simplify it to get: 4x+y=2
