Simplify the expressions and find the value if x is equal to 2 x + 7 + 4 (x – 5) Simplify the expressions and find the value if x is equal to 2 x + 7 + 4 (x – 5)
Dear StudentFrom the question it is given that x = 2We have,= x + 7 + 4x–20= 5x + 7–20Then, substitute the value of x in the equation= (5 × 2) + 7–20= 10 + 7–20= 17–20=-3Thanks
Dear Student x + 7 + 4( x-5) = x + 7 + 4x - 4 × 5 = x + 7 + 4x - 20 = x + 4x +7 - 20 = 5x - 13Now, we find the valu of the expression at x = 2So we put x=2 = (5 × 2) - 13 = 10 - 13 = -3 Thanks
Dear The given expression is:x+7+4(x-5) =x+7+4x-20=5x-13Given that x=2The value=5*2-13=10-13 =-3
