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.
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
1+1+x+x+x+y+y=2+3x+2y
Can you clarify the question please? Is it (14 x 2)-1 + (1x-1) = 3x+1?
2x - 6x + 3x = -412x - 3x = -41-1x = -41x = 41
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
3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4
The expression "negative x plus 3x" can be simplified by combining like terms. Negative x can be written as -1x, so the expression becomes -1x + 3x. When you combine -1x and 3x, you get 2x. Therefore, the simplified expression is 2x.
1+1+x+x+x+y+y=2+3x+2y
y = -1x/2 3x + 6y = 0 -3x -3x __________ 6y = 0 - 3x --- -------- 6 6 y= -3x/6 y= -1x/2
3x

2x - 6x + 3x = -412x - 3x = -41-1x = -41x = 41
To convert 3x to 1x, you can simply divide 3x by 3. This will give you 1x.
3x+7=4x-73x=(-)7+4x-4x(-)1x=(-)7________(-)1x=7add (-3x) to each side of equation3x +7 = 4x-3x +3x +7 = 4x -3x0 +7= 1x7=x
1 -4-3x=4-5 -1x=-1 x=-1/-1 x=1
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
Since x by itself is the same as 1x, the expression can be re-written as 1x+2x Then, ignore the x's and simply add the numbers to obtain 1x+2x=3x 3x is your answer.
