4x=10+3x or 10+3x=4x
Let the unknown number be X: -4x-10 = 2 -4x = 2+10 -4x = 12 x = -3 Remember that a minus multiplied by a minus is equal to a plus: -4*-3 = 12
4x - 10 = -4x + 22 +4x+10=+4x +10 8x = 32 x = 4
3 |4x-10| = 18 |4x-10|=6 4x-10 = 6 4x-10=-6 4x=16 4x=4 x=4 x=1
14
4x - 15 = 5x - 10 5x = 4x - 5 x = -5
If the number is x then: 4x+10 = -2 and so the value of x is -3
0.4
-5x + 2(4x-10)=10
-5x + 2(4x-10)=10
8x + 10 = 3x +145x = 4x = 4/5 = 0.8Improved answer:8x+10 = 4x+148x-4x = 14-104x = 4x = 1
-4x=10 and -7x is 65? -4x=10 therefore 4x is -10, x = -2.5 -7x = 65, 7x = -65, x = -9.26
