10x - 5x + 5x = 10x
5x+5x-10 10x-10 is the only answer you can get from this
5x +12 = -78 -10x +10x +10x 15x +12 = -78 -12 -12 15x = -66 /15 /15 x = 4.4
10x * 5x = 50x2 =====
10x ÷ 5x = 2
10x - 5x + 5x = 10x
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
5x + 10x doesn't need factorization as you can just add them up (5x+10x=15x). However, if you really want to, 5x+10x=5x(1+2)=5x(3)=15x
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
15x
5x+5x-10 10x-10 is the only answer you can get from this
5x + 8xy + 10x + 3xy = 15x + 11xycombine like terms (the x's and the xy's)
5x+8 = 10x+35x-10x = 3-8-5x = -5x = 1 and by substituting the value of x into the equations y = 13
10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
10x - 18 = 5x + 2 Add -5x + 18 to both sides of the equation, to get: 5x = 20, from which x = 4.
