First, write it in a mathematical equation form:4x=2x+14Next, subtract 2x from both sides2x = 14Divide both sides by xx = 7
3x2= 6 6-(4x-2)= 6--8= 6+8 = 14 14+7 = 21
2x + 3 = 72x = 4x = 2
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
