If you mean 49+6 = 4x-7 then the value of x is 15.5
4x + 3, where x = 7 4(7) + 3 = 28 + 3 = 31
4.00
x = 37 4x - 7 = 141 4x - 7 + 7 = 141 + 7 4x = 148 x = 37
sqrt(4x+7) -4 = sqrt(4x-1) squared : (sqrt(4x+7) -4)2 = 4x-1 (4x+7) - 2x4xsqrt(4x+7) +16 = 4x-1 -8xsqrt(4x+7) = -24 sqrt(4x+7) = -24/-8 = 3 squared : 4x+7 = 32 = 9 4x = 9-7 = 2 then x=1/2
If you mean: 4x-14x+7 then the expression can be simplified to 7-10x
If you mean 49+6 = 4x-7 then the value of x is 15.5
4x + 3, where x = 7 4(7) + 3 = 28 + 3 = 31

what is the product of ( 4x-7) (4x+7)
If you mean: 3x -7 +4x = 28 then the value of x works out as 5
27
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
If: 4x-6 = 54 then the value of x works out as 15
4x + 7 = 0 4x = -7 4x/4= -7/4 X = -7/4
7-4x = 3
x = 37 4x - 7 = 141 4x - 7 + 7 = 141 + 7 4x = 148 x = 37
